【Abstract】 A non-linear large strain analysis made on the basis of the total Lagrangian formula and incremental solution strategy is presented in this article.The main ideal for analyzing the problem using the method of gap element s and the stress-strain relationship for the Mooney-Rivlin incompressible material are developed.Based on this theory,the finite element s analysis is carried out for the large strain contact on rubber material and the relation curve between displacements and reactions have been plotted for the cylinder made of rubber material under large strain.The results obtained have established the essential coincidence between computations and testing.更多还原
