A TRIANGULAR DISPLACEMENT-BASED ELEMENT OF THICK/THIN PLATES
-
摘要: 本文构造出了一种具有九个自由度的厚薄板通用三角形位移单元，并给出了单元刚度矩阵显式。这种单元以其简洁的常规位移元列式可在相当宽的板厚变化范围内（包括板厚为零）获得很高的计算精度，其结果可与相应的矩形单元相比。而且不会出现剪切自锁。Abstract: In this paper,a triangular displacement-based element with 9 degrees of freedom for thick/thin plates is developed,and its explicit element stiffness matrix is also presented.This element can obtain high precision with simple formulation for the wide range of plate thicknesses and is free of shear-locking as the thickness of the plate approaches zero.
