ELASTOPLASTIC SINGULAR STRESS FIELD FOR A CRACK MEETING AN INTERFACE BETWEEN TWO LINEAR HARDENING BONDED ATERIALS

摘要：

The elastoplastic stress singularities in a linear hardening bimaterial with an arbitrarily oriented crack meeting an interface are studied.From the compatibility equation and total strain theory,by using Goursat stress functions,the elastoplastie singular stress field is deduced.The results show that the elastoplastic singular stress field can be described with two extended Dundurs parameters related to the hardening coefficients.Especially,when the linear hardening coefficient is far less than the shear elastic modulus,only one extended Dundurs parameter is needed to describe the stress field.
