  2. Yield (engineering) - Wikipedia

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

    The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...

  3. Yield surface - Wikipedia

    en.wikipedia.org/wiki/Yield_surface

    A yield surface is a five-dimensional surface in the six-dimensional space of stresses. The yield surface is usually convex and the state of stress of inside the ...

  4. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus, and Poisson's ratio. In addition, the mechanical element's macroscopic properties (geometric properties) such ...

  5. Factor of safety - Wikipedia

    en.wikipedia.org/wiki/Factor_of_safety

    The yield calculation will determine the safety factor until the part starts to deform plastically. The ultimate calculation will determine the safety factor until failure. In brittle materials the yield and ultimate strengths are often so close as to be indistinguishable, so it is usually acceptable to only calculate the ultimate safety factor.

  6. von Mises yield criterion - Wikipedia

    en.wikipedia.org/wiki/Von_Mises_yield_criterion

    As shown later in this article, at the onset of yielding, the magnitude of the shear yield stress in pure shear is √3 times lower than the tensile yield stress in the case of simple tension. Thus, we have: = where is tensile yield strength of the material. If we set the von Mises stress equal to the yield strength and combine the above ...

  7. Structural engineering theory - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering_theory

    If, for a small increment of displacement the internal work done by the structure, assuming that the moment at every plastic hinge is equal to the yield moment and that the boundary conditions are satisfied, is equal to the external work done by the given load for that same small increment of displacement, then that load is an upper bound on ...

  8. Bond Price vs. Yield: Why The Difference Matters to Investors

    www.aol.com/bond-price-vs-yield-why-140036009.html

    Yield to Call (YTC) – This is similar to the yield to maturity. It is the overall receivable return if the callable bond owner holds it until its call date. Yield to Worst (YTW) – This is the ...

  9. Yield curve - Wikipedia

    en.wikipedia.org/wiki/Yield_curve

    In a positively sloped yield curve, lenders profit from the passage of time since yields decrease as bonds get closer to maturity (as yield decreases, price increases); this is known as rolldown and is a significant component of profit in fixed-income investing (i.e., buying and selling, not necessarily holding to maturity), particularly if the ...
