The dynamic buckling of an elastic-plastic column subjected to axial impact by a rigid body has been discussed in this paper. The whole traveling process of ela
By introducing two displacement functions as well as two stress functions,two independentstate equations with variable coefficients are derived from the three-d
<正>Applying the parametric derivation method,Peierls energy and Peierls stress are calculated with a non-sinusoidal force law in the lattice theory,while the r
