Recently, new 3-node and 4-node MITC shell elements, the MITC3+ and MITC4+ elements, have been proposed. The two shell elements were tested through theoretically well-established convergence studies. In this paper we continue to investigate the perfo

The static modal behavior of the MITC3+ shell element is investigated in detail.We provide insight into how shear locking occurs on the mode level.The performance of the MITC3+ shell element is presented in dynamic mode solutions. In this paper, we i

We present the MITC3+ shell finite element for geometric nonlinear analysis.The Lagrangian formulation is employed allowing for large displacement kinematics.An excellent performance of the element is demonstrated in nonlinear example solutions. In t

In this paper, we present an effective new 3-node triangular shell finite element, called the MITC3+ element. The new shell element is based on the concepts earlier published for the MITC3 shell element (Lee and Bathe, 2004) [1] but is enriched by a

The objective of this study is to improve the performance of the MITC3 shell finite element. The Hellinger-Reissner (HR) variational principle is modified in the framework of the MITC method, and a special approximated transverse shear strain field i

In this paper, we propose a continuum mechanics based 3-D beam finite element with crosssectional discretization allowing for warping displacements. The beam element is directly derived from the assemblage of 3-D solid elements, and this approach res

A new three-field mixed functional is proposed for the analysis of linear elastic problems. The functional is constructed by linearly combining the total potential energy, the Hellinger-Reissner functional, the modified Hellinger-Reissner functional
