Plasticity spreads throughout the solid and at the limit load, the plastic zone becomes very large and the displacements become unbounded and the component is said to have collapsed.

CE — Structural Design and Optimization. Spring, Generally, in plastic analysis, the upper bound theorem is used. It is possible that a mechanism, which would give a lower value of collapse load, has been.

The criteria to be followed in plastic analysis to identify a correct load factor: equilibrium - the Theorem (the lower bound (safe) theorem or static theorem).

Applied Mechanics of Solids. Limit load is the maximum load that a structure can safely carry.
So we can proceed in the analysis. In plastic analysis and design of a structure, the ultimate load of the. Plastic load factor and theorems of plastic collapse Lower bound or Static theorem.
Theorems of Plastic Analysis. Plastic analysis is the method through which the actual failure load of a structure any part of it (Lowerbound Theorem).
The term plastic has occurred due to the fact that the ultimate load is found from the strength of steel in the plastic range.
As the load is increased, there is a redistribution of moment, as the plastic hinge cannot carry any additional moment.
