    some general theorems and generalized and piecewise generalized variational principles for linear elastodynamics

    From the concept of four-dimensional space and under the four kinds of time limit conditions, some general theorems for elastodynamics are developed, such as the principle of possible work action, the virtual ...

    Dynamic analysis of nonlinear systems by modal synthesis techniques

    Different kinds of modal synthesis method have been used widely in dynamic analysis of linear structure systems, but, in general, they are not suitable for nonlinear systems.
