It is possible to stably compute large deformation analysis and coupled problems of nonlinearity (material, geometry, contact) and heat, which are difficult with general-purpose CAE software.
ASU/V-Struct is a high-performance thermal elastoplastic structural analysis program based on V-Struct, developed by the VCAD system research program at the RIKEN Institute. It features a thermal stress-thermal conduction coupled analysis solver that takes into account contact between deformed bodies, contact heat transfer, and pressure application to the processed materials. This allows for the simulation of deformation and residual stress in molded products due to heat in processes such as hot pressing, casting solidification, and resin injection molding cooling, where temperature changes need to be considered. It can also be applied to other areas such as mold deflection, tightening, vacuum forming, and adhesion analysis.

basic information
Main Features of ASU/V-Struct Stability: Based on a static explicit solver developed at the RIKEN National Research and Development Institute, it excels in handling unstable problems involving large deformations! Applicability: To address various challenges in manufacturing processes, we have generously incorporated our CAE element technologies, including contact analysis (rigid and deformable bodies), heat transfer, contact heat transfer, and surface pressure boundaries! Usability: A dedicated pre-post GUI is provided. Even those unfamiliar with analysis can easily use it without resistance. It has a built-in mesher, allowing analysis to start directly from design CAD data.
