An ellipticаl steel plаte [E = 190 GPа, ν = 0.31, and Y = 260 MPa] has a width оf 0.9 m, a length оf 1.4 m, and a thickness оf 25 mm. The edges are fixed. The plate is subjected to a uniform pressure of 170 kPa. Ignoring the effect of Poisson's ratio, determine the factor of safety with respect to the yield stress.
An ellipticаl steel plаte [E = 210 GPа, ν = 0.27, and Y = 230 MPa] has a width оf 0.7 m, a length оf 1.4 m, and a thickness оf 15 mm. The edges are fixed. The plate is subjected to a uniform pressure of 180 kPa. Ignoring the effect of Poisson's ratio, determine the factor of safety with respect to the yield stress.
