By using the formula derived in Part (Ⅰ), the instant response of an unrestrained planar frame structure subjected to the impact of a moving rigid-body are eva
The new orthogonal relationship is generalized for orthotropic elasticity of threedimensions. The thought of how dual vectors are constructed in a new orthogona
A simple and effective boundary element method for stress intensity factor calculation for crack problems in a plane elastic plate is presented. The boundary el
