A Benchmark for 3D Solid Finite Elements using Bending with Shear

A new accuracy benchmark for 3D FEMs based on St. Venant's analytical solution for bending with shear of prismatic bodies is proposed. Tangential forces are acting on both end bases, their distribution across the base is expressed by nonelementary functions. Linearly distributed normal stresses are present only on one end base. Numerical experiments are performed with a tri-cubic Lagrangian rectangular brick element.
