Mesh smoothing algorithm based on exterior angles split.
PLoS ONE, 2020 Since meshes of poor quality give rise to low accuracy in finite element analysis and kinds of inconveniences in many other applications, mesh smoothing is widely used as an essential technique for the improvement of mesh quality.

Connectivity editing for quadrilateral meshes [PDF]
Proceedings of the 2011 SIGGRAPH Asia Conference on - SA '11, 2011 We propose new connectivity editing operations for quadrilateral meshes with the unique ability to explicitly control the location, orientation, type, and number of the irregular vertices (valence not equal to four) in the mesh while preserving sharp edges.

T-Base: A Triangle-Based Iterative Algorithm for Smoothing Quadrilateral Meshes
, 2012 We present a novel approach named TBase for smoothing planar and surface quadrilateral meshes. Our motivation is that the best shape of quadrilateral element (square) can be virtually divided into a pair of equilateral right triangles by any of its ...

An embedded crack model for failure analysis of concrete solids [PDF]
, 2010 We present a quadrilateral fi nite element with an embedded crack that can be used to model tensile fracture in two-dimensional concrete solids and the crack growth. The element has kinematics that can represent linear jumps in both normal and tangential
