A brittle material has the properties S ut = 30 kpsi and S uc = 90 kpsi.
Question:
A brittle material has the properties Sut = 30 kpsi and Suc = 90 kpsi. Using the brittle CoulombMohr and modified-Mohr theories, determine the factor of safety for the following states of plane stress.
(a) σx = 25 kpsi, σy = 15 kpsi
(b) σx = 15 kpsi, σy = -15 kpsi
(c) σx = 20 kpsi, τxy = −10 kpsi
(d) σx = -15 kpsi , σy = 10 kpsi , τxy = -15 kpsi
(e) σx = -20 kpsi , σy = -20 kpsi , τxy = -15 kpsi
