Question:
Consider an extension of Exercise 8.51 in which we wish to explore the stress distribution in a circular disk under an increasing number of boundary loadings. First show that for case:
(a). With four loadings, the center stresses are given by σx = σy =–4P/πD, τ, xy = 0, where D is the disk diameter. Next for case.
(b). With eight loadings, show that the center stresses. become σx = σy =–8P/πD, τ, xy = 0. Hence conclude that for a general case with N loadings (N = 4, 8, 16,.), the center stresses can be expressed by σx = σy=–NP/πD, τ, xy = 0. Thus
as N → ∞, the boundary loading becomes uniformly distributed as shown in case.
(c). And center stresses are then given by σx =σy=–p, τ, xy = 0 where p = NP/πD, which can be found from solution (8.4.3).
