Sentence examples for fatigue constraint from inspiring English sources

It is a special structural optimization problem because of the existence of the implicit fatigue constraint.

In addition, as an aggregated fatigue constraint is very sensitive to the changes in stress value which causes some unstable convergences in optimization process, a new scaling approach of the aggregated fatigue damage constraint is developed.

For the topology optimization for fatigue constraint, we use transient stress analysis to extract effective stress cycles and Miner's cumulative damage rule to calculate total damage at every spatial element.

In addition to the numerical and theoretical issues associated with static failure criteria, we found that the local mode issue and the non-differentiability of the fatigue failure criteria needed to be addressed prior to performing fatigue constraint topology optimization.

This paper describes a weight reduction problem of aluminum disc wheels under cornering fatigue constraints.

The existence of fatigue constraints may change both optimal stacking sequences and buckling modes.

In this research, a new layout optimization method is developed to consider high cycle fatigue constraints which occur due to variable amplitude mechanical loading.

The design is particularly challenging in view of the ITER environment of particle, heat and neutron fluxes, temperature cycles, electromagnetic loads, vibrations, expected material degradation and fatigue, constraints against tritium penetration, integration in the plug and limited opportunities for maintenance.

Because the calculation of the exact sensitivities of a transient system is complex and time consuming for the topology optimization application, this research proposes to use the pseudo-sensitivities of fatigue constraints calculated by applying equivalent static load approach.

Although fatigue is a very important property in terms of safety when designing mechanical components, it has rarely been considered in topology optimization with the lack of concept and the difficulty of sensitivity analysis for fatigue constraints calculated from multiaxial cycle counting.

46 Owing to the time and fatigue constraints of respondents considered above, only a subset of the full design will be shown to each participant.
