文摘An interfacial crack is a common damage in a composite material structure . An extended propagation model has been established for an interfacial crack to study the dependence of crack growth on the relative sizes of energy release rates at left and right crack tips and the properties of interfacial material characterize the growth of interfacial crack better.
文摘By using Galerkin’s method, the finite element formulation is made for axisymmtric heat transfer problems for anisotropic materials from the heat transfer differential equations expressed in terms of heat fluid density. Results of an example show that the heat transfer anisotropy has an important effect on temperature field.
