Continuum structural topological optimizations with stress constraints based on an active constraint technique [PDF]
International Journal for Numerical Methods in Engineering, 2016 SummaryStressârelated problems have not been given the same attention as the minimum compliance topological optimization problem in the literature. Continuum structural topological optimization with stress constraints is of wide engineering application prospect, in which there still are many problems to solve, such as the stress concentration, an ...

Energies, 2023 A piezoelectric energy harvester (PEH) transduces mechanical energy into electrical energy, which can be utilized as an energy source for self-powered or low-power devices. Therefore, maximizing the power of a PEH is a crucial design objective.

Rhythmic constraints on English stress timing [PDF]
4th International Conference on Spoken Language Processing (ICSLP 1996), 1996 The evidence for isochrony of stress timing is weak for ordinary prose, but this does not mean that the timing of stresses is always unaffected by global constraints. We asked subjects to continually repeat the phrase "Take a pack of cards" and to temporally align the words "take" and "cards" with an auditorily presented stimulus consisting of just the

Influence of residual stress on apparent fracture toughness of pipeline under different constraints
Advances in Mechanical Engineering, 2022 Taking the cracked pipeline as the research object, different preloads were applied on the cross section of the pipeline to produce different stresses at the crack tip, and these stresses were introduced into the pipeline as the residual stresses by ...

Stress-activated constraints in dense suspension rheology
Physical Review Fluids, 2022 Dispersing small particles in a liquid can produce surprising behaviors when the solids fraction becomes large: rapid shearing drives these systems out of equilibrium and can lead to dramatic increases in viscosity (shear-thickening) or even solidification (shear jamming).

Stress-constrained shell-lattice infill structural optimisation for additive manufacturing
Virtual and Physical Prototyping, 2020 This paper presents a numerical study on stress-constrained shell-lattice infill structural optimisation. This problem is inherently challenging for several reasons: (i) different stress measures have to be used for the solid shell and the porous lattice
