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.
You can tackle simulations involving material failure and look at how this 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 simulated accurately. Using computers with higher numbers of CPU cores can drastically reduce solution times.
Sheet Metal Forming Analysis & Manufacturing Process Simulation
One of Ansys LS-DYNA’s most widely used applications is sheet metal forming. LS-DYNA accurately predicts the stresses and deformations experienced by the metal to determine if it will fail. It also supports adaptive remeshing, refining the mesh during sheet metal forming analysis, as necessary, to increase accuracy and save time.
Metal forming applications include:
- Metal stamping
- Deep drawing
- Multi-stage processes
Ansys LS-DYNA’s electromagnetism (EM) capabilities for modelling eddy currents can be used to simulate magnetic metal forming, welding and induced heating processes.
Nonlinear Structural Analysis
Ansys LS-DYNA can perform simulations of mechanisms involving joints and articulations subjected to impacts (whether from drops or collisions). It can utilize joints and kinematic links, and offers a wide choice of contact formulations to easily and automatically take into account interactions between all components in the model. When this is combined with LS-DYNA’s fast and efficient explicit solver scheme, it gives you unrivalled simulation capabilities to study situations that could not be solved using implicit FEA methods.
Soil Structure Interaction
Ansys LS-DYNA’s novel method for soil–structure interaction analysis applies earthquake forces in an efficient, rational manner and models the unbounded domain accurately at low computational cost, given a free-field ground motion characterizing an earthquake.
Ansys LS-DYNA is the primary crash simulation and analysis tool for over 80% of the world’s major automotive OEMs, and the code is used by an estimated 90% of tier 1 suppliers.
Ansys LS-DYNA is used to predict a car’s behavior in a collision and the effects of a collision upon the car’s occupants. Such analyses encompass a wide variety of complex physical phenomena, and LS-DYNA is equipped with a vast array of features and capabilities to replicate these events.
Ansys LS-DYNA is widely used by the aerospace industry to simulate bird strikes, jet engine blade containment and structural failure analysis. Aerospace simulation applications include:
- Blade containment
- Bird strike (windshield and engine blade)
- Failure analysis
