1、材料力学上机大作业一、题目要求：应力状态分析应力状态分析输入:1.平面应力状态输入：（σx、σy、τxy）；某截面方位角α2.空间应力状态输入（σx、σy、σz、τxy、τyz、τzx）输出：1.输出主应力（σ1、σ2、σ3）2.最大切应力[τmax=τ13=（σ1-σ3）/2]3.如为平面应力状态则需输入方位角α斜截面上的应力σα、τα及主方向角α0。4.画出应力圆示意图，如为平面应力状态则需标明斜截面上的应力σα、τα对应点及半径程序：由matlAB程序GUI功能实现可视化窗口，使界面更加友好。程序分为三个部分：1.主页；2.平面应力计算；3.空间应力计算。
2、在主页可以选择进入平面应力计算或是空间应力计算，从平面或空间应力计算也可以返回主页。下面是程序代码：1.主页：functionvarargout=zhuye(varargin)%ZHUYEMATLABcodeforzhuye.fig%ZHUYE,byitself,createsanewZHUYEorraisestheexisting%singleton*.%%H=ZHUYEreturnsthehandletoanewZHUYEorthehandleto%theexistingsingleton*.%%ZHUYE('CALLBACK',hObject,eventD
