Numerical Solution and Parameter Analysis of Structure with Different Modulus

Materials with different modulus in tension and compression have a wide application in engineering practice, especially the composite materials developed in recent years, which have properties of different tension-compression modulus. To exploring the general features of mechanical properties of structures with different modulus, the dimensionless equation of finite element was deduced for structure with different modulus, and corresponding finite element program was developed .the stresses of the cantilever beam by program of the theory with different modulus. The impacts on member stresses resulted from the change of structure size, external load and the ratio of different modulus are compared and analyzed. Finally, we have drawn a conclusion that the property of different modulus of the material is very important to its stress, and have given out suggestions on the optimization of state of structural stress.
