3. Abending member with a rectangular cross section is made of ABS plastic and has dimensions, as defined in Fig. 8.13(a), of b = 28 mm and t = 10 mm. For a safety factor against brittle fracture of 3.2, determine the largest through-thickness edge crack length, a, that can be allowed if: a. M = 15 N·m. b. M = 4.0 N-m. 4. What are the safety factors against fully...

2. (15 pts) A tension member made of 18-Ni maraging steel (air melted), (properties in table 8.1), has a length of 1200 mm, a width of 100 mm, and a thickness of 15 mm. It may have a through thickness edge crack that measures 15mm in length as shown in figure 8.12(c). What tension force P can be allowed for a safety factor against brittle fracture in stress (%) of 3.0?

1. AA 6061, a high-strength aluminum alloy, has a 0.2% offset yield strength of 37,500-psi and a plane strain fracture toughness (Kic) 26,400-psi (inch) At a service stress equivalent to 80% of the yield strength, will this structure fracture if it contains an edge crack of length 2.24-inches. Assume that the geometric factor, f, is 1.12. 2. A steel alloy, which has a plane strain fracture toughness (Kle) of 49-MPa(m) is exposed to a service stress of 1010-MPa. Is fracture...

The stainless steel and polystyrene rulers in Example 5.2 are loaded as cantilevers of length 250 mm. Both have sharp transverse scratches of depth 0.2 mm, near the base of the cantilever on the tensile side. For this surface crack geometry, assume the factor Y in equation (8.4) is 1.1. The fracture toughness K1c of steel and polystyrene are 80 and 1 MPa.m", respectively. Calculate the stress needed to cause fast fracture in each case. Will the cantilevers fail by...
