  2. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    Tensile stress is the stress state caused by an applied load that tends to elongate the material along the axis of the applied load, in other words, the stress caused by pulling the material. The strength of structures of equal cross-sectional area loaded in tension is independent of shape of the cross-section.

  3. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.

    • Torsion, flat plates, and columns • Shells of revolution, pressure vessels, and pipes • Bodies under direct pressure and shear stress • Elastic stability • Dynamic and temperature stresses • Stress concentration • Fatigue and fracture • Stresses in fasteners and joints • Composite materials and solid biomechanics

  5. Euler's critical load - Wikipedia

    en.wikipedia.org/wiki/Euler's_critical_load

    The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally. The critical load puts the column in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. As the load is increased beyond the ...

  6. Fatigue limit - Wikipedia

    en.wikipedia.org/wiki/Fatigue_limit

    Representative curves of applied stress vs number of cycles for steel (showing an endurance limit) and aluminium (showing no such limit).. The fatigue limit or endurance limit is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. [1]

  9. Permissible stress design - Wikipedia

    en.wikipedia.org/wiki/Permissible_stress_design

    Wood, steel, and other materials are still frequently designed using allowable stress design, although LRFD is probably more commonly taught in the USA university system. In mechanical engineering design such as design of pressure equipment, the method uses the actual loads predicted to be experienced in practice to calculate stress and ...
