A first order elastic analysis of a rigid -jointed frame is based on the assumptions that: The material behaves linearly, so that all yielding effects are ignored. The members behave […]
EK137
Theoretically, a member can only behave linearly while the maximum stress does not exceed the yield stress, and so the presence of residual stresses or stress concentrations will cause early […]
EK45
Let the beam be subjected to bending in the plane of symmetry. If the bending moment is small, the stress and the strain vary linearly across the section. When the […]

The principle of superposition states that when the structure behaves linearly the total deflection caused by forces at any point is the sum of deflection caused by forces acting independently.
