These numerical investigations are performed in the velocity range from 800 m/s to 1300 m/s. The target plate with a thickness of 15mm and the spherical projectile with a diameter of 10mm are modelled using three-dimensional elements (3D) in a Lagrangian formulation. A hydrostatic tensile stress failure model combined with the Johnson and Cook constitutive model is used to highlight the dynamic failure of the target. The different failure mechanisms observed on the Aluminum plate from the moment of impact to full perforation are discussed. The numerical results based on the crater diameter at the front and rear surface of the plate and the dimensions of the penetration channel are compared to the experimental data available in literature.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121328075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And through SHPB impact compression test, the mechanical properties of Ti/PTFE energetic materials under a high strain rate (1*103- 3*103) at room temperature was analyzed. Furthermore, the impact-induced reactivity of Ti/PTFE energetic materials was investigated through a quasi-sealed chamber test.

Combining large deformations, numerous interface productions and strong damages mechanism, those events are numerically challenging. Eulerian finite element methods are classically used. However, they induce very long computation times, accuracy losses and need opening criteria to deal with failure. Among the Lagrangian approaches the meshless methods called Smoothed Particle Hydrodynamics appears as a relevant alternative to prevent such shortcomings. We propose to use an alternative scheme called   -SPH-ALE. Based on the ALE framework, it achieves robust and consistent stabilization through an arbitrary description of motion. Its implementation on a Viper shaped charge shows that the scheme handles the jet generation process as well as its resulting interaction with an ERA target. Both stability and accuracy are increased with respect to classical approaches. Also, taking advantage of GPU computing, such results are achieved in reduced computation times with respect to classical CPU implementations.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117167718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The type of interaction between the jet and the flying plate depends on several variables such as the velocity, thickness, obliquity of the flying plate, and the velocity and diameter of the incoming jet. In this study, four modes of interaction between jet and flyer plate, and necessary conditions for each mode of interaction are proposed, depending on the flyer plate and hypervelocity parameters. Then, these conditions are proved with a simulation study. Simulation results are examined both qualitatively by the deflection of the jet and quantitatively by comparison of momentum transfer on the jet. It is seen that conditions for interaction modes are in agreement with simulation results.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115536063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, detection, localization, and the shock loadings on a target ship due to explosion caused by an underwater multi-influence bottom mine containing most advanced PBX-charge have been studied. It was found that the keel shock factor (KSF) value is   0.50 kg1/2m-1 up to the water depth of 70 m. The shock wave energy at 70 m water depth is 14.8 kJm-2 where KSF equals to 0.50 kg1/2m-1. For a target ship, a significant drop in the blast pressure wave value (8.5-3.4 MPa) between the stern to the bow is noticeable with the total duration of shock loading of 0.0362s. The method proposed in the present study could be used for quick and reasonably accurate estimation of the impact of an incident shock wave underwater on the target ship.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127234586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Standard IB models assume that grains are symmetric with no variation in dimensions, with instantaneous homogeneous ignition. This paper evaluates the contribution of grain dimensional variation (specifically the web), asymmetry and flame spread in a single base propellant with a single perforated grain geometry. It is shown that flame spread has the dominant effect on burn time, followed by web dimensional variation and lastly asymmetry. The implementation of these effects also leads to a simulated result that is more representative of the experimental curve in the closed vessel especially in the burnout phase.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125862962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to improve the accuracy and the effectiveness of weapons, a wear analysis is deemed essential. The main aim of this research is the establishment of a new wear quantification technique using the profilometry method to quantify the influence of erosion on the performance of the gun. Thus, a Zeiss Micura Coordinate Measuring Machine (CMM) equipped with the VAST XTR gold high-end sensor and two NATO small caliber guns (5.56x45 mm and 7.62x51 mm) are considered. In order to quantify their wear volume after every N shots cycle, firstly, a new measurement approach is developed. Secondly, an uncertainty analysis is carried out for each measurement. Finally, a piezoelectric high-pressure transducer is used to measure the pressure inside the barrels after each CMM measurement. In order to evaluate the relationship between the latter and the wear volume, an experimental database is developed. The results show a similar correlation for the two NATO small caliber guns.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122802027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is to achieve increased performance results as well as low temperature and pressure sensitivity characteristics. Theoretical estimates of heat formation for these molecules were made and propellant performances were calculated. In these materials, as the oxygen balance was decreased, a lower temperature sensitivity could be achieved as well as a higher specific impulse and an increase in the drop height. The propellant should have a high but steady burn rate that exhibits low-pressure and temperature sensitivity. The main objective of this study is to characterize and evaluate a new energetic plasticizer. This will be comprised of a eutectic mixture of linear dinitrodiazaalkanes energetic materials, named as DNDA-57.
