Simplified modelling of joints and beam-like structures for BIW optimization in a concept phase of the vehicle design process
TL;DR: In this paper, an engineering approach for the replacement of beam-like structures and joints in a vehicle model is proposed, based on the reduced beam and joint modelling approach, which involves a geometric analysis of beam member cross-sections and a static analysis of joints.

Analysis of and workarounds for element reversal for a finite element-based algorithm for warping triangular and tetrahedral meshes
TL;DR: Sometimes FEMWARP reverses elements; this is the main concern in this paper, and several techniques are proposed to make the method more robust against reversals.
