Oasys LS-DYNA Environment: User Guide (Version 8.1) LS-DYNA Manual Section: *CONTROL_SHELL Example of: Hemispherical Load Example Filenames: hemi_load.key Description: A spherical shell is subjected to two outward point loads on the x-axis and two inward point loads on the y-axis. Model: The 1/8 symmetry model of a sphere measures 10 inches in radius with a thickness of 0.04 inches. The model contains 48 shell elements. A force of one pound is applied in the positive x-direction to the node on the x-axis. A force of one pound is applied in the negative y-direction to the node on the y-axis. The calculation terminates at 0.018 seconds. Input: The element formulation used is the Hughes-Liu shell. If the Belytschko Tsay shell was used the Belytschko-Wang-Chiang warpage stiffness option (*CONTROL_SHELL) would also have to be use. The concentrated loads are applied to two nodes (*DEFINE_CURVE, *LOAD_NODE_POINT). Results: The oscillation of the node on the z-axis shows a regular oscillatory behavior. Reference: Belytschko, T., Wang and Chiang. Page A.67
