SIMPLIFIED LIMIT LOAD DETERMINATION USING THE REFERENCE TWO-BAR STRUCTURE

摘要

Limit loads for mechanical components and structures are determined in this paper by invoking the concept of equivalence of "static indeterminacy" that relates a multidimensional pressure component configuration to a "reference two-bar structure." Simple scaling relationships are developed that enable the rapid determination of limit load multipliers. The reference two-bar structure method is applied to a number of pressure component configurations with or without notches.
