BIAX Lab

  • Profile and Objective

    To shorten product development cycles and minimize trial costs, the behavior of components is simulated on the computer in advance.

    The accuracy of the finite element simulations depends on the selected material model and in particular on the quality of the material parameters. The biaxial testing machine LFM-BIAX can be used to determine material parameters for highly nonlinear materials.
