摘要
对弹性体中的一点在三向应力状态下进行分析,并求解该弹性体的主应力。运用矩阵方法,求应力矩阵的特征值,得到该弹性体的主应力就是应力矩阵的特征值,应力主方向就是相应特征值的特征向量的结果。
This paper considers three-dimensional stress at the point of elastic body. By using the method of matrix, the eigenvalues of this stress matrix are solved. Main stress of the elastic body is eigenvalues of the stress matrix, while the main direction of stress corresponds to eigenvector of the stress matrix. The result is of significance in the theory and application of mechanics.
