Designing for Strength: ASME’s DBA Guidelines and Beyond
- 730 Downloads
Finite element stress analysis is carried out with the aim of assessing the strength of structural and other load-bearing components. It is an essential feature of structural mechanics that the stress values cannot be taken at their face value. Damage which can be caused by stress of a given magnitude is strongly dependent on the nature of stress distribution and the loads causing them. These issues are addressed in ASME’s Boiler and Pressure Codes, Section VIII, Div. 2 which is referred to as Design by Analysis (DBA) guidelines. In this paper, the guidelines are assessed by carrying out elastic-plastic analysis.
