【Abstract】 This paper introduces the mechanical calculation model,the constraint condi-tions,the adopted elements and the main points of the program. It subsequently lists the chief formulas,emphasizing the derivation of elastic matrix and the stiffness submatrix ior the transverse isotrqpic laminated structure. Then,;it indicates the flow chart of the program,and briefly describes the subprograms related to the formation of stiffness submatrix and to the solution of large scale simultaneous equation’s with limited capacity. It finally discusses the debugging of the program and analyzes the calculated results.更多还原
