A 50mmx50mmx50mm cube of graphite-reinforced material (note principal material axis are oriented along the cubes faces)...
A 50mmx50mmx50mm cube of graphite-reinforced material (note principal material axis are oriented along the cubes faces) is extended in the 1-direction by 0.50mm and is constrained against contraction in the 3 direction. The cube is free to contract or expand in the 2- direction. A) What is the change in the dimension of the cube in the 2- direction, b) determine the stresses in the 1 and 3 direction required to produce this deformation
