The non-Newtonian fluid in the collision

摘要

This paper studies elastic-plastic material deformation in terms of Cauchy and PTT. It gives certain convergence to the equation analysis in the discrete finite element method; it reaches o (h~2+Δt) under the certain step length. Then we carry on Three-dimensional numerical simulation by the high performance software LS-DYNA and the distribution of stress and strain curve is observed.
