摘要
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. (C) 2003 Elsevier Science Ltd. All rights reserved.
