Weight‐Minimal Laminate Structures Under Stress Constraints
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001AbstractThe determination of weight‐minimal laminate structures requires the well‐aimed employment of structural optimization. In contrast to the common parameter optimization in which the design variables fiber orientation and layer thickness are varied continuously, a layerwise topology optimization offers more flexibility.

The Mechanics of Constraint Materials: Stress, Strain and Failure of Constraint Networks
This document establishes the complete constraint-network foundation for solid mechanics within the Energy-Efficiency Theory (EET) framework. Every major phenomenon in classical materials mechanics --- elastic deformation, plastic flow, yield, work hardening, the Bauschinger effect, necking, adiabatic shear banding, strain gradient plasticity, damage ...openaire +1 more source
Constraints on patterns of primary and secondary stress
2003This dissertation examines the interaction of various phonological phenomena with stress assignment. In some languages primary and secondary stresses behave identically or symmetrically with respect to a particular process. However, in other languages, only primary stress undergoes the process while secondary stress does not. In these languages, stress

Uncertainty‐oriented thermoelastic topology optimization with stress constraint
International Journal for Numerical Methods in EngineeringAbstractThe material redistribution abilities of traditional deterministic topology optimization are effective in addressing stress‐related design issues in thermal elastic structures. However, uncertainties are inevitable in real‐world. The structural strength of a design, achieved through deterministic topology optimization, is highly susceptible to ...
