WebThree nonlinear shell theories for analysing buckling of spherical shells will be employed in this paper. The rationale for doing so is to establish the range of applicability of the two most commonly used sets of nonlinear buckling equations—small strain–moderate … WebThe formula for the Euler buckling load is 10. (10.6) f c = − k π 2 E I L 2, where E is Young's modulus, I is the moment of inertia of the column cross-section, and L is column length. The value of k varies with the end conditions imposed on the column and is equal to the values given in Table 10.1. Table 10.1.
