Analysis of Stress and Deformation of Layered Beam Based on Block Element Method

LU Xiao-min;YUAN Tao;Department of Engineering Mechanics,Hohai University;  
Based on block element method,deformation mode included rigid displacement,constant strains and curvatures was constructed. The equilibrium equations were conducted by principle of minimum potential energy. The displacement and stress under blanced load of simple beam were calculated. The results of block element method show that stress and displacement are very close to theoretical values only with fewer elements,and the stresses in interface elements have more accuracy yet alway it will be the upper limit of theoretical value. Besides,the stress accuraly is very high,which can ensule the reliability in simulating the damage of the contact surface. To analyze nonlinear material mechanics,yielding and cracking in interface elements were simulated. Yielded criterion used M-C formulation principle and cracked condition used the principle that the max-tensile stress in interfaceelement exceeds maximum tensile strength. Using the computer program of upper method,the stress and deformation of a layered cantilever beam were studied under uniform pressure. The results are correct and show that the method of the paper is feasible.
