Stress and Strain Tensors in 3D - Engineering

This engineering video covers a tutorial on how to derive and visualise the stress and strain tensors in 3D Cartesian coordinates. Stresses and strains develop internally in a body that is subjected to external loads. Multi-variable calculus is used to derive the axial and shear strains, which are the partial derivatives of the displacements. The shear deformations of an element cut out from a 3D body is sketched in the xy, xz and yz planes for better visualisation of the strain deformations.
