Unformatted text preview: • A 2D state of stress relative to one Cartesian coordinate system can be related to those of other Cartesian coordinate system sharing a common origin. • The only parameter that relates the two systems is the rotating angle. • 3D state of stress has similar transformation. • Stress is defined at every point in continuum body. • Stress components are not unique, they depend of the coordinate system. • Once the components of a coordinate are know, the others in other coordinate can be calculated through transformation. • These transformation is valid for any solid or fluid material, as long as continuum assumption is satisfied. • A shearless state of stress corresponding to one coordinate is not shearless in other coordinate. • Derive equations (2.13) through (2.22) • Example Stress transformation Stress transformation Stress transformation Stress transformation...
