Aluminium alloys and advanced high-strength steels (AHSS) are extensively used in the automotive industry because of their exceptional formability and strength-ductility balance. This study investigates the influence of microstructure and deformation mechanisms on the forming limit curve (FLC) of representative automotive steels (SAPH 370, DP 780, DP 980, TRIP 780, and TWIP 940) and aluminium alloys (AA5182 and AA2024-O). The tensile uniform elongation, post-uniform elongation, and associated mechanisms such as dislocation slip, mechanical twinning, and transformation-induced plasticity are analysed to establish their relationship with FLC₀ (plane strain forming limit). Uniaxial tensile parameters are used to create a predictive model that connects FLC₀ to both uniform and post-uniform elongations. Experimental results demonstrate that post-uniform elongation plays a dominant role in governing FLC₀, being nearly 3.5 times more influential than uniform elongation. Although TWIP and TRIP steels have a high total elongation, their limited post-uniform deformation results in moderate FLC₀ values. In contrast, SAPH and DP steels exhibit moderate total elongation with appreciable post-uniform elongation, resulting in comparatively higher FLC₀. In aluminium alloys, limited strain-hardening and low normal anisotropy reduce FLC₀, whereas cryogenic conditions suppress dynamic recovery and thereby improve FLC₀. The proposed model offers a unified framework to predict formability from tensile elongations, showing strong agreement with experimental FLCs for both steels and aluminium alloys.</div></div>","PeriodicalId":52306,"journal":{"name":"International Journal of Lightweight Materials and Manufacture","volume":"9 3","pages":"Pages 337-347"},"PeriodicalIF":0.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147800676","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 work investigates the mechanical properties and energy absorption capabilities of AlSi10Mg strut-based and Triply Periodic Minimal Surface (TPMS)-based lattice structures with different topologies. Specifically, the study included 9 lattice geometries: strut-based designs such as Body-Centered Cubic (BCC), BCC with Z-struts (BCCZ), and Rhombic Dodecahedron (RD); as well as TPMS-solid and TPMS-sheet structures of I-graph-wrapped package (IWP), Diamond, and Gyroid. First, the alloy’s microstructure was examined, and then the stress-strain curves and deformation modes of the lattice structures were analyzed. Regression models were derived from the experimental data to predict the first peak stress, elastic modulus, and energy absorption of lattice structures. Finally, the absolute and specific properties of AlSi10Mg lattices were compared with each other and with lattices made of different alloys from the literature. The results showed that TPMS-sheet lattice structures have the highest absolute and specific properties. TPMS-sheet Diamond lattice structures with a 0.2 relative density have an elastic modulus of 603.6 MPa, a first peak stress of 37.15 MPa, and a volumetric energy absorption of 21.44 MJ/m³. They deformed in a stretch-dominated behavior. BCCZ lattice structures had comparable mechanical properties, but their energy absorption was hindered by the buckling of the vertical struts and subsequent catastrophic failure of the lattice.</div></div>","PeriodicalId":52306,"journal":{"name":"International Journal of Lightweight Materials and Manufacture","volume":"9 3","pages":"Pages 300-313"},"PeriodicalIF":0.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147800759","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}

FE analysis of the SC plate revealed failure modes that informed the design of improved lattice structures, while preserving the original relative density and stiffness. Weak regions were reinforced by redistributing material, introducing 2D lattice-inspired columnar supports that enhance the structural integrity of the 3D plate lattice. A suite of structural configurations including unit cells, compression-, and beam-lattices were fabricated via material extrusion additive manufacturing, with optimized parameters for closed-wall geometries without support structures. Quasi-static tests highlighted increases of 150 % and 53 % in buckling strength for the optimal unit cell and lattice, respectively, while the beam lattice enhanced the bending load capacity by 46 % over the baseline value. This enhanced performance arises from an improved load distribution and the suppression of multi-mode buckling through 2D lattice-inspired columns, increasing axial strength without compromising the stiffness of the plate-based architecture.

Investigating Polysulfone (PSU) in material extrusion (MEX) 3D printing is challenging due to processability issues. Therefore, it is still inadequately studied, while the 3D printing parameters are expected to affect its mechanical performance. To examine the influence of critical process variables on the mechanical and thermal properties of HPP PSU samples, a series of test specimens were fabricated using the MEX 3D printing technique. A comprehensive experimental design modeling approach, specifically the Taguchi L16 method, was employed. Five control factors, each at four levels, were considered: raster angle, head speed, nozzle temperature, fill density, and strand width. The mechanical response of the printed specimens was evaluated through measurements of tensile strength, Young's modulus, tensile toughness, and tensile yield strength. The experimental data also facilitated the application of two regression models to interpret the obtained results. The thermal stability and phase transition of PSU were examined using differential scanning calorimetry and thermogravimetric analysis. The microstructural characteristics of the printed parts were evaluated via scanning electron microscopy. Optimization achieved more than 200 % improvement in three of the four response metrics (163 % in the fourth one). Prediction models achieved less than 10 % error in confirmation runs, while R² was found to be higher than 85 % confirming the prediction accuracy.

This study investigates the high-temperature mechanical response of AA6082 through Gleeble uniaxial tests with digital image correlation (DIC), focusing on strain localisation and strain rate evolution. The experimental results reveal non-uniform strain distribution and significant strain localisation at elevated temperatures, with higher temperatures leading to earlier strain localisation and deviations from the target strain rates.

A new fitting technique considering varying strain rates has been proposed to refine constitutive modelling, improving the accuracy of calibration. A near-perfect plasticity behaviour is revealed for AA6082 under constant strain rates at high temperatures.
