A tensile test yields the following data on a sample:Initial cross section: 100 mm2Elongation at failure: % 5Force at failure: 22,000 NThe sample is known to have a KIC of 40 MPa m1/2 and a Poisson ratio of 0.3.a) What could be the critical crack size for the sample tested?b) To use this material in an application with a safety factor of 3, what is theminimum cross section area?
