Abstract: The r-nodes (redistribution nodes) are locations in mechanical components and structures that are load-controlled, and therefore insensitive to material constitutive relationships. These locations ...

Abstract: Part 1 of the article provides the theoretical underpinnings of a new method to determine statically admissible stress distributions in a structure, called bounded elastic moduli multiplier technique (BEMMT). It is shown ...

Abstract: Statically admissible stress distributions are necessary to evaluate lower bound limit loads. Over the last three decades, several methods have been postulated to obtain these distributions using iterative elastic finite ...

Abstract: A simple procedure uses the r-nodes to achieve minimum weight design of mechanical components and structures. The method is based on two linear elastic finite element analyses (or more) in ...

Abstract: Conventional analysis of tubesheets in nuclear steam generators involves elastic analysis of a solid plate with equivalent properties. It has recently been recognized that alternate design techniques ...
