Question: 4 the displacement field in a body is given as...

Question details

4. The displacement field in a body is given as where U, V, and W are the displacements in the x, y, and z directions respectively. (a) Calculate the strain components at point (1,0,2) (b) What is the extension of a line element of length dX parallel to the x-axis, at this point. (c) What is the extension for a line element of length dL at 30° to the x-axis on the xy-plane Note: Stress and strain tensors follow the same equations of coordinate transformation. Please recall, to follow the same equations of transformations a stress, the shear strains γ n. ,, ,7xz need to be replaced by En,--,є,-_.cxz--]
