Lovadina C., Auricchio F. On the Enhanced Strain Technique for Elasticity Problems. Preprint ercim.cnr.ian//2002-1297, 2002.
The Enhanced Strain Technique is considered in the context of incompressible elasticity problems. A new triangular element is proposed and proved to be convergent and stable when applied to linear analysis. Moreover, a model problem arising from large deformations is presented. Such a model is used to develop some theoretical considerations about the use of Enhanced Strain methods in nonlinear elasticity.
