✦ Synopsis

This work presents the results from a set of veri"cation shell problems used to assess the performance of the higher-order shear deformation shell elements formulated in Part I of the present study. The developed element has been added to the element library of the nonlinear dynamic explicit "nite element code DYNA3D. Several standard veri"cation test problems are performed using the code DYNA3D with the developed shell element. Results are presented for di!erent test problems and are compared with experiments and results from other existing shell elements. The good overall performance builds con"dence in the formulation and implementation of the proposed higher-order shear deformable element. The superior advantage of the developed element is evident in one of the examples presented for representation of plastic #ow through the thickness in isotropic materials. The element can be used in crash and metal forming simulations in local areas of high transverse shear stresses. Local areas of crack in crash applications and splitting in metal forming applications can be modeled more accurately with the developed shell element.
