Sentence examples for maximum normal strain from inspiring English sources

By considering the combined influence of singular (KI) and first non-singular (T) components in the crack tip stress/strain field, the KIc data obtained from these two specimens were predicted by means of the maximum normal strain theory.

The optimum method for crack initiation life prediction for complex multiaxial variable amplitude loading was found to be a critical plane approach based on maximum normal strain plane and damage quantification by cracking energy density on that plane.

This proposed approach consists of the maximum shear strain range, the normal strain range and the maximum normal stress on the maximum shear strain range plane.

Additionally, in order to preserve the unitless feature of strain, the maximum normal stress is normalized by the material yield strength.

A wide range of test data is used to evaluate the approach as well as a critical plane approach based on maximum amplitude of shear strain modified by the maximum normal stress on the plane of maximum shear strain amplitude.

In this parameter, shear strain amplitude has a primary influence on fatigue damage and the maximum normal stress on the maximum shear plane has a secondary, but important, influence.

However, the best fit with the reference scatter band is realized by the application of the maximum shear and normal strain energy density parameter in the critical plane.

On the basis of the investigation on the Kindil Brown Miller and Fatemi Socie's critical plane approaches, a shear strain based multiaxial fatigue damage parameter was proposed by von Mises criterion based on combining the maximum shear strain and the normal strain excursion between adjacent turning points of the maximum shear strain on the critical plane.

The modified damage parameter combined maximum shear strain range with normal strain range on the critical plane, and a new stress-correlated factor is introduced to account for the additional cyclic hardening.

Then a modified low cycle fatigue life prediction model is put forward in which the sum of maximum shear strain range and normal strain range based on the critical plane concept is adopted to replace the uniaxial strain range used by Stolkarts et al. [Stolkarts, V., Keer, L.M., Fine, M.E., 1999.

The effect on fatigue life of normal strain or stress on the maximum shear strain plane is found rather small for critical plane theories.
