Limit load estimation for structures under mechanical loads. - 210 p.

Source: Dissertation Abstracts International, Volume: 65-03, Section: B, page: 1516.

Thesis (Ph.D.)--Memorial University of Newfoundland (Canada), 2003.

Limit analysis is germane to the assessment and design of mechanical components and structures. Among the various methods for limit load estimation, robust methods based on linear elastic finite element analysis are appealing to analysts and designers due to the conceptual insight, economy of computational effort and wide applicability.

520 $a Limit analysis is germane to the assessment and design of mechanical components and structures. Among the various methods for limit load estimation, robust methods based on linear elastic finite element analysis are appealing to analysts and designers due to the conceptual insight, economy of computational effort and wide applicability.
520 $a A robust limit load estimation scheme based on the extended Mura's variational principle that is used in conjunction with repeated elastic finite element analyses (FEA) is developed in this thesis. The secant modulus of individual elements in a finite element discretization scheme is prescribed to account for the plastic flow variation in a component or structure. The multipliers m0 and m' obtained using this formulation converge rapidly to the exact value with the use of repeated elastic FEA. Using the notion of "leap-frogging to limit state," an improved lower-bound multiplier malpha can be obtained. This method is applied to several component geometric configurations made of isotropic materials.
520 $a The method is further extended to layered structures, cracked components and components made of anisotropic materials. For all these applications, the multipliers m0, m ' and malpha predicted by the proposed procedure are compared with those obtained by the lower bound estimation based on the elastic compensation method (ECM) and inelastic FEA. The results show that the robust method developed in this thesis can be applied to various components and structures leading to good limit load estimates.
