Abstract: A new approach is proposed to estimate the fracture of bodies with V-shaped notches under loading of two types. Two examples of quasibrittle fracture are considered: with an initial straight crack and with a sharp V-notch. Experimental data are obtained on the fracture of V-notched specimens under bending.
Keywords: V-notch, strain energy density, loading schemes of the first and second types, quasi-brittle fracture, initial direction of crack propagation, local fracture criterion.
