The tungsten-rhenium thermocouple was used to measure the internal explosion temperature history within the chamber. It is revealed that the measured temperature was enhenced with the increase of mass of outer layers. When the ratio increased from 0.39 to 0.68 and 1.52, the peak temperature increased from 329K to 517K and 882K, respectively. It is revealed that the excessive mass of layers are not conducive to the full release of energy generated from combustion. It is found that the layer with an aluminum powder size of 10μm exhibits the best effect on raising the temperature after the explosion, indicating that the medium-sized aluminum powder can fully react with detonation product and release more heat, which is beneficial to realizing the thermal radiation damage.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"3 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":"126722581","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 blast loading is applied using an Explosive Driven Shock Tube (EDST) [10-12] which ensures a uniformly distributed blast wave on the test specimens. Experiments were carried out for different sizes, positions, and numbers of the predrilled holes in the plates positioned at the end extremity of the tube. Special focus is dedicated to investigate the influence of these parameters on the dynamic response and failure characteristics of plates via the Digital Image Correlation technique (DIC).

The design of an antielectromagnetic launch overload structure draws much attention in the field of the fuze. In this paper, anti-high overload structure of the fuze is designed by analyzing the environmental factors in the electromagnetic launch. Then mechanics analysis and calculation are investigated. Nextly, the finite element simulation model is established. Based on this model, the stresses and deformations of the fuze in different protective conditions are analyzed during a high overload environment. The best protective scheme is selected. The theoretical calculation and simulation analysis results show that the max stress of the structure is less than the tensile strength of the material and the deformation is very small. Finally, the experiment of the electromagnetic launch is executed, and verification of the fuze is ultimately performed. In conclusion, the designed structure of the fuze can meet the anti-high overload requirement.","PeriodicalId":211716,"journal":{"name":"Proceedings of the 32nd International Symposium on Ballistics","volume":"1 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":"129257016","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 effects of fragments on the process of impacting target plate at different initial velocities were analyzed by combining theory and numerical simulation.

Stepped-top obturators resulted in higher average pitch values than flat-topped obturators. Single piece obturators of acetal or UHMWPE appeared to provide equivalent behavior; acetal appears to be more brittle than UHMWPE, but was easier to machine to tolerance. Two-part obturators functioned reliably and were less prone to result in secondary impact on targets. Aluminum and steel pusher plates offered comparable performance for the projectile and launch velocity considered. A Garolite G-11 composite pusher plate didn’t prove strong enough to function correctly.

However, it is often difficult to analyze the impact process of the reactive projectile on the plate. Its complexity lies in the fact that the process of the reactive projectile penetrating the plate depends not only on its kinetic energy, but also on the chemical energy released by the reactive material under strong transient load. In this paper, Ballistic limit behavior of reactive projectile impacting thin aluminum plate was studied, ANSYS/LSDYNA was used to obtain the ballistic limit of reactive projectile impacting thin aluminum plate. Meanwhile, based on the critical stress/strain rate activation hypothesis of reactive materials, the ballistic limit of reactive projectile is analyzed by one-dimensional shock wave theory.
