Steady states in severe plastic deformations and microstructure at normal and high pressure

Journal of Materials Research and Technology
The main fundamental problem in studying plasticity and microstructure evolution is that they depend on five components of the plastic strain tensor εp, its entire path εppath, and pressure p and its path ppath, which leaves little hope of finding some ...

Effect of grain angle on the strain distribution during orthogonal cutting of hinoki (Chamaecyparis obtusa) measured using a digital image correlation method

Journal of Wood Science, 2019
The strain associated with orthogonal cutting with and against the grain of hinoki (Chamaecyparis obtusa) was measured. Digital image correlation method was used to measure strain distributed in the area within 0.5 mm of the cutting edge.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

The Path to Triacylglyceride Obesity in the sta6 Strain of Chlamydomonas reinhardtii [PDF]

Eukaryotic Cell, 2014
ABSTRACT When the sta6 (starch-null) strain of the green microalga Chlamydomonas reinhardtii is nitrogen starved in acetate and then “boosted” after 2 days with additional acetate, the cells become “obese” after 8 days, with triacylglyceride (TAG)-filled lipid bodies filling their ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Experiment and Crystal Plasticity Simulation of Forming Limit of Quenching Partitioning Steel

Shanghai Jiaotong Daxue xuebao
Quenching-partitioning (QP) steel combines ultrahigh strength with good ductility due to the martensitic transformation during plastic deformation. However, the formability of the QP1180 steel remains unclear.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Numerical analysis of strain path dependency in FCC metals

, 2008
Strain path dependency in FCC metals is often associated with the anisotropy induced by the dislocation cell structure in deformed metals. In this paper, the mechanical behaviour of metals under various nonuniform deformation paths is studied with the ...

Study of Work-Hardening Rate Transient of AISI 409 Stainless Steel Under Strain Path Changes [PDF]

Materials Research
Metal forming processes present many changes in the strain path necessary to obtain the dimensions and shape of a metal part. The loading mode, the amount of prestrain, the initial state of a material and its respective substructural arrangements affect ...
