Full Transcript

The stress tensor and strain tensor are introduced for the three dimensional state of stress and strain in a solid. The normal stress, shear stress, normal strain and shear strain are introduced. The Hooke's law is presented in 3D and the elastic compliance matrix and elastic stiffness matrix are introduced. The 21 elastic constants for anisotropic materials are identified. #aerospaceengineering #structuralmechanics #solidmechanics
