摘要: Presents recent advances obtained by the authors in development of enhanced strain finite elements for deformation problems. Discusses two options, both involving simple modifications original enhancement strategy gradient as proposed previous works. The first new is based on a full symmetrization interpolation fields; second involves only transposed part these fields. Both lead to significant improvement performance problems high compressive stresses, showing particular mode‐free response, while maintaining and efficient (strain driven) numerical implementation. Demonstrates properties with number benchmark simulations, including complete modal analysis elements.
