Mechanics of Materials & Deformable Bodies

Stress-strain behavior, axial load, pure bending, shear stresses, beam deflections, and torsion.

Theory Modules

Study the theory, review the governing formula, and test your knowledge with interactive questions.

Axial loading is a force acting along the longitudinal centroidal axis of a prismatic member, producing uniform norma...

Bending arises when a beam carries transverse loads that produce internal bending moments. Under the assumptions of E...

Buckling is a sudden, catastrophic failure mode characterized by lateral deflection (bending) of a structural member...

Beam deflection is the transverse displacement of a beam caused by applied loads. It is a serviceability quantity tha...

Shear stress τ is the internal resistance to sliding between adjacent layers of a material. It acts parallel (tangent...

Stress and strain are fundamental concepts in mechanics of materials. Stress (σ) is the internal resistance per unit...

Torsion is twisting of a member by a torque T about its longitudinal axis. For a circular shaft, cross-sections remai...
