CAE tools can now also simulate the composition of elastomers, in particular Elastollan, BASF's thermoplastic polyurethane (TPU)
.
One of the special features of simulation with Ultrasim is the option to simulate both the initial load and the cyclic load of the components
.
The performance characteristics of elastomers often include stress softening (Mullins effect) under cyclic loading
.
However, the simulation usually starts from the initial processing stage, which can accurately predict the warpage behavior during injection molding, taking into account the complex viscoelastic behavior of the material
.
“The simulation tool Ultrasim provides our customers with fast and reliable information on how BASF’s materials will behave during production and later in life for their planned components
.
BASF is the first material producer to offer such extensive simulation services in the TPU sector
.
Elastollan is used in automotive parts such as strain relief sleeves on electrical connectors, spring isolators on axles, folding bellows and end stops for shock absorbers
