The Damage Finite Element Analysis of Eutectic Composite Ceramic Containing Lamellae

摘要

According to microstructures in eutectic composite ceramic,the finite element model of composite with eutectic interphase is established.The mechanical stress field of eutectic composite ceramic containing lamellae is simulated.APDL programming in ANSYS is used to analyze the damage process of eutectic composite ceramic.Results show that the failure of eutectic composite ceramic is determined by the damage of matrix.As load is increasing,the damage will elongate along the interphase and extend to the internal of matrix.At last the damage arouses matrix fracture.
