Question: part 1 develop a userdefined function of the matrix iteration...

Question details

Part 1: Develop a user-defined function of the matrix iteration method (oower method) for solving a standard eigenvalue problem associated with the square matrix A, i.e. finding all of its eigenvalues and eigenvectors. You may use the MATLAB function eig to check your results in the debugging. Also, debug your function using a matrix whose size N>3. Part 2: The status of stress at a point in an elastic body is given by 4-23 σ-1-2 5 2|MPa 3 22 Find the principal stresses and the associated principal directions of the given stress tensor. Part 3: The von Mises stress is defined by @w--1 y@ _ σ2 ) 2 + (o,-ON + (o, _ σ.)2 where σ (i-1,2,3) are the principal stresses. For a ductile material, a failure criterion can be expressed by where σ,-10MPa (academic value) is the yielding stress of the material obtained from a uni-axial testing. Determine if the material fails at the above point with the given state of stress
