Experimental study of high temperature mechanical and fatigue behaviours of sicp_a356 composites for brake disc
Mechanical and low cycle fatigue behaviours of SiCp_A356 composite at room and elevated temperature are investigated by experiments. The yield stress, tensile stress and Young’s modulus drop obviously with the rising temperature. The hardening cycle occurs between 200C and 1500C, but weakens with rising temperature. The softening cycle appears between 2000C and 3000C, but increases with rising temperature. The relaxation performance is similar to that of a standard metal material. The low cycle fatigue behaviour of SiCp_A356 agrees with the equation of Manson-Coffin, which is severely affected by temperature, especially for small strain amplitudes. The cyclic thermal elasto-plastic and creep constitutive models are presented for the brake disc stress-strain analysis and life prediction. Finally the micro fracture mechanics is analyzed.

Abstract
Mechanical and low cycle fatigue behaviours of SiCp_A356 composite at room and elevated temperature are investigated by experiments. The yield stress, tensile stress and Young’s modulus drop obviously with the rising temperature. The hardening cycle occurs between 200C and 1500C, but weakens with rising temperature. The softening cycle appears between 2000C and 3000C, but increases with rising temperature. The relaxation performance is similar to that of a standard metal material. The low cycle fatigue behaviour of SiCp_A356 agrees with the equation of Manson-Coffin, which is severely affected by temperature, especially for small strain amplitudes. The cyclic thermal elasto-plastic and creep constitutive models are presented for the brake disc stress-strain analysis and life prediction. Finally the micro fracture mechanics is analyzed.
