Ansys LS-DYNA is the most commonly used explicit simulation program, capable of simulating the response of materials to short periods of severe loading. Its many elements, contact formulations, material models and other controls can be used to simulate complex models with control over all the details of the problem.
Ansys LS-DYNA has a vast array of capabilities to simulate extreme deformation problems using its explicit solver. Engineers can tackle simulations involving material failure and look at how the failure progresses through a part or through a system. Models with large amounts of parts or surfaces interacting with each other are also easily handled, and the interactions and load passing between complex behaviors are modeled accurately. Using computers with higher numbers of CPU cores can drastically reduce solution times.

Sheffield Hallam University
Sheffield Hallam University researchers used ANSYS LS-DYNA explicit dynamics software to simulate tennis racket–ball impacts to gain a better understanding of the physics involved in the racket’s performance. The tennis equipment manufacturer, Prince Sports, has begun making low-friction strings based on the results of this study. View Case Study
