In the present paper, based on the theory of dynamic boundaryintegral equation, an optimization method for crack identification is set up in theLaplace frequenc
The coexisting periodic impacting motions and their multiplicity ofa kind of dual component systems under harmonic excitation are analytically derived.The stabi
Rigid Finite Element Method(RFEM)was proposed to simulate themechanical behavior of discontinuous structures such as rock and soil structures.Theauthors’ work
In this paper,by means of combining non-probabilistic convex model-ing with perturbation theory,an improvement is made on the first order approximatesolution in
