Shearing deformations in beamsse shear strains, could be replaced by “the beam is made of a material with an infinite shear modulus.” Because such a constitutive law is awkward, the transverse shear force (the stress resultant associated with the shear stress), is not evaluated from this constitutive law but from equilibrium con

Linear elasticity solutionso-dimensional problems featuring cylindrical symmetry reduce to ordinary differential equations. It is often necessary, however, to reformulate the elasticity equations in cylindrical or spherical coordinates to take advantage of specific symmetries or easily impose boundary conditions.

Buckling of beamsred beam subjected to an end axial compressive load. If this load is applied at the centroid of the cross-section of the beam, it creates only an axial straining of the beam. As the axial compressive load is increased, a critical value is reached when the beam buckles sideways and collapses.
