COMPRESSION INSTABILITIES OF TISSUES WITH LOCALIZED STRAIN SOFTENING [PDF]
International Journal of Applied Mechanics, 2011 The stress–strain relationship of biological soft tissues affected by Marfan's syndrome is believed to be nonconvex. More specifically, Haughton and Merodio recently proposed a strain energy density leading to localized strain-softening, in order to model the unusual mechanical behavior of these isotropic, incompressible tissues.

Flow softening mechanism in isothermal compression of β-solidifying γ-TiAl alloy
Materials & Design, 2020 Flow softening mechanism in the isothermal compression of Ti-42.9Al-4.6Nb-2Cr with duplex structure was investigated. True stress-strain curves of Ti-42.9Al-4.6Nb-2Cr exhibited evident flow softening behavior when isothermal compression was conducted at ...

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Journal of Materials Research and Technology, 2021 Softening mechanism and microstructure evolution of 2A14 aluminum alloy were studied via isothermal deformation tests under the temperatures range from 573 K to 773 K and strain rates range from 10−3 s−1 to 1 s−1. Microstructures indicated that the grain

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Advanced Engineering Materials, EarlyView.This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight
