[Other] Plane-continuum-FEM-analysis DL : 0: 正方形薄板四周受均匀载荷的作用，该结构在边界上受正向分布压力，同时在沿对角线y轴上受一对集中压力，载荷为2KN。由于连续平板的对称性，只需要取其在第一象限的四分之一部分参加分析，然后人为作出一些辅助线将平板“分割”成若干部分，再为每个部分选择分析单元。采用将此模型化分为4个全等的直角三角型单元。利用其对称性，四分之一部分的边界约束，载荷可等效如图所示。-Square plate under uniform load around the role of the structure of the distribution on the boundary by positive pressure, while the y axis along the diagonal by a Pair of pressure, load the 2KN. The symmetry of the continuous plate, whichever is only one quarter in the first quadrant of some of the participants, and then make some people will flat guides " split" into several parts, and then select the unit of analysis for each section. Using this model is divided into four congruent right-angle triangle unit. Use of its symmetry, a quarter part of the boundary constraints, loads can be equivalent to as shown.
