What is plastic analysis?

Plastic analysis can be defined as the analysis of inelastic materials which are studied beyond their elastic limit. Plastic analysis is defined as the analysis in which the criterion for the design of structures is the ultimate load. Plastic analysis has its application in the analysis and design of indeterminate structures.
