... of loading: in-phase and out-of-phase cycling. The article illustrates the ways in which damage can interact at high and low temperatures and the development of microstructurally based models in parametric form. It presents a case study of the prediction of residual life in a turbine casing of a ship through...

... and tolerances (i.e., parametric or parameter design). Designers and materials engineers are key participants in this iterative process, and failure analysts also need to appreciate and understand the roles and activities of the design process. This provides the basis to identify possible technical root...

It is used again and again in recursive fashion for the conceptual stage to select materials and processes, to configure parts, and to assign numerical values to dimensions and tolerances (i.e., parametric or parameter design...

... by considering the effects of tensional, shear, torsional, and bending stiffnesses, along with the contact and friction between wires. Stanova et al. [ 9 , 10 ] used geometric parametric equations to model some single and multilayered strands. They used MATLAB, CATIA, and ABAQUS software techniques to construct...

Change in elastic modulus with temperature cannot be neglected at higher homologous temperatures. Parametric modeling of creep or stress-rupture behavior often normalizes...

Parametric modeling of creep and stress-rupture behavior often normalizes the stress with the modulus. One way to avoid creep failure is to select the proper material based on parametric...

... normal stress reaches the yield strength of the material. Tresca’s theory states that yield at a point begins when the maximum shear stress equals the shear stress in a tension specimen when it begins to yield. Another common failure model is the von Mises criterion, which is based on a determination...
