efficient than the formulation in ANSYS based on GEBF. Key words: recursive formulation; multibody dynamics; large displacement beam; corotational frame Cite this article as: WU Tan-hui, LIU Zhu-yong... of beam elements were proposed by BELYTSCHKO [2, 18]. To consider large displacement, the inertial frame approach is commonly applied. Two kinds of formulations are suggested among them. One......
thickness of 0.5 m was proposed tentatively, entering the calculation parameters to calculate stresses in subgrade soil and displacement of beam foundation with various widths under upper loads of 28 t. Under beam foundation of 1.8 m in width, the calculation vertical stress in subgrade was 236 kPa, the vertical displacement of foundation was 6.5 cm, and the plastic shear zone went completely through......
