NON-LINEAR FINITE ELEMENT CAPABILITIES

Pioneer has available in-house an implicit FEA (ABAQUS) as well as an explicit FEA (LS-DYNA 3D) solvers.  Each one is suited for special types of non-linear FEA analyses.  In some areas their capabilities overlap. In addition to these, the I-DEAS Master Series has a suite of FEA modeler, and a Linear FEA solver.   This combination allows us to handle just about any structural problem, of any type, starting with the Master Series CAD.

ABAQUS "Standard" is an implicit FEA solver with its own modest pre-processor, robust solver, and a powerful post-processor.  It handles almost all problems of static non-linear problems, viscoelasticity, plastic deformation, linear and non-linear buckling, post-buckling, modal dynamics, linear and non-linear dynamics, fatigue, thermal transients and thermal stress. 

Thus, it is readily seen that a large number of structural and thermal analysis problems of the industry - both metals and plastics - can be solved using ABAQUS. 

LS-DYNA 3D is an explicit solver, and is eminently suited for complex dynamics, vibration and wave propagation problems.  Its explicit algorithm can be used effectively for high speed impact, shock and vibration  problems.  Falling impact, rubber elasticity, impact on sports goods (rackets, bats, helmets) are typical examples of problems that can be handled by LS-DYNA 3D accurately.  This is also a favorite program of the automobile industry for the crashworthiness analysis, as well as the effectiveness of airbags and seat-belts.

Both these programs can take input from I-DEAS model files, after a translation stage.  Alternatively, Pioneer can also work with the IGES model of any client-developed CAD.
