Orion space craft water and land landing system simulation; An injury case study
NASA’s return to moon program had kept the NESC (NASA Engineering and Safety Center) busy for the past several years. The NESC was charged to come up with a safe landing for the Orion capsule. Water and land landing is considered for ...

Validation and Material Modelling of Plastics
The virtual estimation of physical product properties is only as good as the virtual description of the behaviour of its material. On the one hand there are well known material cards like *MAT_PIECEWISE_LINEAR_PLASTICITY in LS-DYNA© ...

A constitutive model for thermoplastics with some applications
A constitutive model for thermoplastics is outlined in this paper. The model consists of two parts: A hyperelastic-viscoplastic response due to intermolecular resistance denoted Part A, and an entropic hyperelastic response due to ...

A new advanced Visco-eleastoplatic eight chain rubber model for LS-DYNA
A new advanced eight chain rubber model has recently been implemented in LS-DYNA. The material is tailored for polymeric materials. The basic theory is taken from Arruda’s thesis from 1993 but it has been enhanced with advanced ...
