 note = {application/pdf, In the present paper, temperature dependence of damage on CFRP laminates subjected to collision of steel ball was considered from viewpoint of impact load and impulsive stress. The histories of impact load and transverse stresses in a CFRP laminate are analyzed theoretically by means of three-dimensional theory and Hertzian analysis of contact with anisotropic thermoviscoelastic property. Impact damages were generated by collision of steel ball under various thermal conditions. As a result, the maximum of transverse stresses subjected to collision of steel ball are influenced by impact load and they suddenly decrease over the primary glass transition temperature. When transverse stresses are compared with delaminations, large transverse shear stress occurs in the direction where delamination progresses greatly. Therefore the direction to progress of a delamination is explained by the transverse shear stress distribution. And the transverse stresses and delamination areas are small under high thermal environments., Article},
