Prediction of self-heating measurements under proportional and non-proportional multiaxial cyclic loadings

Strain gradient plasticity under non-proportional loading

A critical examination is made of two classes of strain gradient plasticity theories currently available for studying micrometre-scale plasticity. One class is characterized by certain stress quantities expressed in terms of increments of strains and their gradients, whereas the other class employs incremental relationships between all stress quantities and the increments of strains and their g...

Stress and Strain Analysis of Notched Bodies Subject to Non-Proportional Loadings

Abstract—In this paper, an analytical simplified method for calculating elasto-plastic stresses strains of notched bodies subject to non-proportional loading paths is discussed. The method was based on the Neuber notch correction, which relates the incremental elastic and elastic-plastic strain energy densities at the notch root and the material constitutive relationship. The validity of the me...

Non-proportional Shrinkage Compensation

Shrinkage and warpage is a leading fact in casting. It is common to compensate shrinkage by scaling the tool by a certain percentage. The transformed 3D CAD model of a final product is used for tool generation. The transformations of CAD model include 3D scaling or external surface offset. Both methods are proportional and uniform in all three axes, and they are already included in a vast varie...

Point Prediction for the Proportional Hazards Family under Progressive Type-II Censoring

In this paper, we discuss dierent predictors of times to failure of units censored in multiple stages in a progressively censored  sample from proportional hazard rate models. The maximum likelihood predictors, best unbiased predictors and conditional median predictors are considered. We also consider Bayesian point predictors for the times to failure of units. A numerical example and a Monte C...
