8- and 12-node plane hybrid stress-function elements immune to severely distorted mesh containing elements with concave shapes
TL;DR: In this article, the authors improved the first version of hybrid stress element method proposed by Pian and developed several 8 and 12-node plane quadrilateral elements, which are immune to severely distorted mesh containing elements with concave shapes.

TL;DR: This work presents a method for measuring the viscoelasticity in subcortical gray matter structures, including the amygdala, hippocampus, caudate, putamen, pallidum, and thalamus, based on incorporating high spatial resolution MRE imaging with a mechanical inversion scheme designed to improve local measures in pre‐defined regions (soft prior regularization [SPR].

Combined shape and topology optimization of 3D structures
TL;DR: This tool can be used to improve the stiffness of a structure before printing, reduce the amount of material needed to construct a bridge, or to design functional chairs, tables, etc. which at the same time are visually pleasing.
