  2. Buckling - Wikipedia

    en.wikipedia.org/wiki/Buckling

    Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. . Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capac

  3. Structural engineering theory - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering_theory

    A column under a centric axial load exhibiting the characteristic deformation of buckling. When subjected to compressive forces it is possible for structural elements to deform significantly due to the destabilising effect of that load. The effect can be initiated or exacerbated by possible inaccuracies in manufacture or construction.

  4. Tension member - Wikipedia

    en.wikipedia.org/wiki/Tension_member

    In an axially loaded tension member, the stress is given by: F = P/A where P is the magnitude of the load and A is the cross-sectional area. The stress given by this equation is exact, knowing that the cross section is not adjacent to the point of application of the load nor having holes for bolts or other discontinuities. For ex

  5. Structural load - Wikipedia

    en.wikipedia.org/wiki/Structural_load

    [1] [2] A load causes stress, deformation, displacement or acceleration in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements. Excess load may cause structural failure, so this should be considered and controlled during the design of a structure.

  6. Stress (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Stress_(mechanics)

    Stress in a material body may be due to multiple physical causes, including external influences and internal physical processes. Some of these agents (like gravity, changes in temperature and phase, and electromagnetic fields) act on the bulk of

  7. Timoshenko–Ehrenfest beam theory - Wikipedia

    en.wikipedia.org/wiki/Timoshenko–Ehrenfest_beam...

    Physically, taking into account the added mechanisms of deformation effectively lowers the stiffness of the beam, while the result is a larger deflection under a static load and lower predicted eigenfrequencies for a given set of boundary conditions. The latter effect is more noticeable for higher frequencies as the wavelength becomes shorter ...

  8. Deformation (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deformation_(engineering)

    By convention, the strain is set to the horizontal axis and stress is set to vertical axis. Note that for engineering purposes we often assume the cross-section area of the material does not change during the whole deformation process. This is not true since the actual area will decrease while deforming due to elastic and plastic deformation.

  9. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    Strain, or reduced deformation, is a mathematical term that expresses the trend of the deformation change among the material field. Strain is the deformation per unit length. [ 9 ] In the case of uniaxial loading the displacement of a specimen (for example, a bar element) lead to a calculation of strain expressed as the quotient of the ...
