A PMMA plate with a 25 mm (width) x 6.5 mm (thickness) cross-section has a contained crack of length 2c = 0.5 mm in the center of the specimen. If the applied load (along the 2 length direction) is 1000 N, calculate the stress intensity factor. If the fracture toughness of PMMA, K1c = 1.15 MPa.m1/2, at what load (in N) does the crack propagate?
| A three point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5,0mm; the specimen fractured at a load of 3000 N when the distance between the support points was 40mm. Another test is to be performed on a specimen of this same material, but one has a square cross section of 15 mm length on each edge. At what load would you expect this specimen to fracture if the support point...
please answer both the questions Question 2 A titanium tube 200mm diameter and 5mm wall thickness is subjected to an internal pressure of 13.5MPa. The tube contains a longitudinal crack along its full length. Assuming that the tube can be approximated by a single edge notched plate subjected to a tensile stress equal to the hoop stress in the tube determine the crack length to cause failure. You may assume that the material fracture toughness is 55 MPavm. Please provide...
