Study on the Response of Composite Material Cylinder with Metal Liner under Thermal Mechanical Impact

Article Preview

Abstract:

As to the composite cylinder with metal liner under the high temperature and high pressure, thermal mechanical coupling mechanism and response are studied. On the basis of equations for coupling thermal and mechanical impact load and the non-linear thermoelastic finite element equations, the 3-D analysis model of the composite cylinder is established by using the finite element method. The direct coupling analysis is conducted and the variation regularity of the dynamic stress field is obtained. The results show that the thermal mechanical impact loads can cause large transient stress, which influences the strength of the metal liner obviously.
