Abstract

Based on the finite element method and theory of structural mechanics

static and dynamic stress of the Ti/TiC laminated composites were investigated by ANSYS software

and the finite element model was established.The results show that the mechanical properties of Ti/TiC laminated composites are improved significantly compared with those of Ti.When the thickness-layer ratio is 2∶1

the simulated bending strength of laminated composite reaches 1 684.26 MPa

which is closed to the experimental value 1 571.51 MPa.Under impact loading

the six order modal values of Ti/TiC laminated composites are the higher

so it is difficult to generate the resonance

and more energy can be converted into potential energy with less absorption.
