- I'm wondering the direction the normal stress should be shown on a deformed material element.
Let's say you have a material element with normal and shear stress. These stresses were computed using stress transformation. When the material deforms, should the normal stress vectors remain normal to the surface (sketch 1) or parallel to the other surface (sketch 2)? Which would be more accurate? Thanks!
