2.3.6 Tip in-plane shear load on a cantilevered hook

Product: ABAQUS/Standard  

The Raasch Challenge problem has been used as a test for in-plane shear loading in a curved strip using shell elements (see Knight, 1997). Transverse shear flexibility and proper treatment of twisting deformations of the shell elements are important factors in determining the bending behavior.
