(d). A ceramic bar of diameter do = 5 mm has a fracture toughness Kic
= 2.35 MNm-3/2. If this bar is subjected to a tensile force F of 1800
N, determine the maximum, permissible length of an infinitely
sharp crack both on the surface and inside the material before
brittle fracture.
Suatu bar seramik berdiameter do = 5 mm mempunyai nilai keliatan
patah K1c = 2.35 MNm-3/2. Sekiranya bar ini dikenakan daya
tegangan F 1800 N, tentukan panjang maksima dibenarkan I bagi
retak tajam tak terhingga pada permukaan dan di dalam bahan
sebelum berlakunya patah rapuh.
