DETERMINING CONCRETE STRAIN-SOFTENING CURVE BY THE J-INTEGRAL METHOD
With the ordinary material testing machine, the fracture testing results of the concrete wedge splitting specimen are presented in this paper. Consistent load-displacement curves are obtained, and the fractUre toughness JIC,δC, fracture energy GF are determined,then the concrete strain-softening curve is deduced by using the J-integral method.
