Question: A specimen made from a brittle material with a cross-section area of 0.004 m2 was gradually loaded in tension until it yielded at a load

A specimen made from a brittle material with a cross-section area

A specimen made from a brittle material with a cross-section area of 0.004 m2 was gradually loaded in tension until it yielded at a load of 380kN and fractured slightly after the yield point. If the specimen's material observed elastic deformation until fracture, determine the material's toughness in terms of the energy absorbed, in kJ. Take E=200GPa
