SAFE AND RELIABLE DESIGN METHODS FOR METALLIC COMPONENTS AND STRUCTURES DESIGN METHODS

摘要

Tools available for structure design are various and are different according to the fact that the risk is associated with an eventual presence of defect and possibility of brittle fracture or a ductile failure. The following design tools are described: (1) allowable stress and safety factor, (2) linear fracture mechanics and safety factors, (3) crack driving force, (4) failure assessment diagram, (5) allowable strain, (6) critical gross strain, (7) strain based design.
