LARSTRAN

The load carrying capacity of a structure undergoing severe deformation (including plastic strain) can only be determined by using non-linear numerical calculations. For structural analysis of smaller deformations, non-linear calculations may also produce more accurate results than linear calculations. Such calculation methods made some tasks like designing and dimensioning of spring elements with non-linear characteristics possible. Similar calculation methods are also used to analyse sheet-metal forming phenomena and to compute the flow of material while drop forging.

LARSTRAN - Shape is a modular software program, which has been optimised for structural analysis, but can easily be extended to use for other types of problems. It incorporates independent data management with emphasis on the solving of non-linear structural problems.

It can generate solutions for various applications including statics, stability (such as post-buckling behaviour), implicit dynamics, slow viscous flow, non-linear transient heat transfer and thermo-mechanical coupling.
