Ansys Autodyn
Short Duration, Severe Loading Simulations

Simulate the response of materials to events ranging from short duration severe mechanical loadings, high pressures and even explosions. Ansys Autodyn provides advanced solution methods without compromising ease of use.

Overview

Expertly Handle Your Simulations of Complex Material Response

Ansys Autodyn makes it easy to quickly understand and simulate large material deformation or failure. Autodyn has a range of models to represent complex physical phenomena such as the interaction of liquids, solids and gases; the phase transitions of materials; and the propagation of shock waves.

A Range of Solver Schemes Integrated into One Product

The smooth particle hydrodynamics (SPH) solver completes the picture to provide everything needed for explicit analysis. Ansys Autodyn lets you select from different solver technologies so the most effective solver can be used for a given part of the model.

The Lagrangian FE solvers enable fast and efficient solutions when looking at structural components subjected to shock loading and large deformations. Two Euler solver formulations give you the ability to model high speed fluid flow, as well as an alternative way to simulate extreme plastic flow of solid materials.

Solver Coupling

Autodyn’s interaction logic enables automatic communication between the various solvers for coupling of fluid-solid interaction (FSI) models for blast, erosion, impact and multiscale simulations of high-speed events.

Lagrange-Lagrange, SPH-Lagrange and Euler-Lagrange interactions can all be created within the model in a simple and intuitive manner. This allows fluid structure interactions to be simulated with ease.

Material Data

The response of materials to dynamic high strain rate loading can be complex, and the necessary material data is hard to come by.

To help you with this, Autodyn’s material library contains over 150 prepopulated material models covering most common engineering alloys, brittle and granular materials, orthotropic materials and energetic and explosive compounds.

This combination of models gives you the ability to simulate various material phenomena such as nonlinear pressure response, strain hardening, strain rate hardening, thermal softening, compaction of porous materials, orthotropic behavior, crushing damage, chemical energy deposition, tensile failure and phase changes.

Integration into Workbench

Ansys Autodyn is integrated into Ansys Workbench, taking advantage of CAD import, geometry clean up, model set up, material definition and interoperability with other Ansys analysis systems.
