Abstract: This report,aiming at laminated plates made of composite material,has developed a new finite clement analysis method by establishing stiffness matrixes of isoparametric, solid elements, superparametric shell elements, solid-shell trasi-tion elements and elements with out-element ncdes.These elements are available to analysing isotropic/orthotropic material,honeycomb sandwich and/or composite plates. They are able to represent complex structures distinctly and solve the significant subject in composite material research--inter-layer stress analysis. From an engineering application point of view.the maximum strength of, various structures mentioned above is studied and a method solving non-lin,ear problem of composite material is suggested.Also,some of the analysed examples are given at the end of the article.It is shown that the method is very effective.
