DOI: 10.1007/s12206-020-0822-z
Abstract: In the structural analysis of thin elastic structures using standard FEMs within the poor approximation space, the numerical results may suffer from the quality deterioration called the locking phenomenon. This situation becomes more crucial for… read more here.
