In recent years, the explicit dynamic finite element method has been widely used in the field of collision impact and has shown advantages in dealing with large-scale contact problems. ANSYS/LS-DYNA is a general explicit nonlinear dynamic finite element program, and can solve a variety of nonlinear problems such as the nonlinear contact of high- speed collisions, explosions, and metal forming in three- dimensional nonlinear structure, the impact of load nonlinearity and material nonlinear problems.
Collisions and impacts are a transient complex physical process, which is a Non-linear dynamics problem. The explicit dynamics finite element method in LS-DYNA is mainly used in solving the problems of collision.
The images at right are a small sampling of what is possible to simulate using this technology. a short video I made a short video demonstrating an everyday phenomenon is here. A slow motion version is here.
Explicit dynamics from ANSYS enables the creation of virtual prototypes of designs operating under real-world extreme environmental conditions. ANSYS Explicit STR provides to the analysis industry the explicit component of the most advanced unified simulation environment known as the ANSYS Workbench platform.
Industry-leading solver technology is the basis for ANSYS Explicit STR, solver technology that has been forged through more than 20 years of commercial usage.
CAD connectivity and automatic meshing with advanced options.
User programmability, macros, and scripting allow simulation customization to suit almost any need.
