In a rigid body or in an unconstrained deformable body, the application of a moment of force causes a pure rotation. But if a deformable body is constrained, it develops internal forces in response to the external force so that equilibrium is maintained. An example is shown in the figure below. These internal forces will cause local deformations in the body. WebBeam section behavior. Defining a beam section's response to stretching, bending, shear, and torsion of the beam's axis requires a suitable definition of the axial force, N; bending moments, M 11 M 11 and M 22 M 22; and torque, T, as functions of the axial strain, ε ε; curvature changes, κ11 κ 11 and κ22 κ 22; and twist, ϕ ϕ.
