Nuclear Materials and Energy, 2022 A multiscale crystal plasticity finite element model, which combines molecular dynamics with crystal plasticity theory, is proposed. In this model, the evolution equations for partial- and full-absorption dislocation loops are utilized.

Materials Theory, 2017 The standard way of modeling plasticity in polycrystals is by using the crystal plasticity model for single crystals in each grain, and imposing suitable traction and slip boundary conditions across grain boundaries.

On the Plasticity of Crystals [PDF]
Physical Review, 1935 In the following, a theory is given with the purpose of establishing a mathematical relation between the stress and the strain in a crystal when plastically deformed. The existence of a "secondary structure" in crystals is adopted as a basic hypothesis. This structure was pointed out by Professor F.

Avalanches and plastic flow in crystal plasticity: an overview [PDF]
Modelling and Simulation in Materials Science and Engineering, 2017 Abstract Crystal plasticity is mediated through dislocations, which form knotted configurations in a complex energy landscape. Once they disentangle and move, they may also be impeded by permanent obstacles with finite energy barriers or frustrating long-range interactions.

Investigation into the Effects of Prior Plasticity on Creep Accumulation in 316H Stainless Steel
Physical Sciences Forum, 2022 Steel components in the boilers of nuclear reactors are subject to high temperatures and varying loading conditions. This can introduce time-dependent and time-independent plasticity, which can interact with one another.

Metal Crystal/Polycrystal Plasticity and Strengths
Metals, 2022 A brief historical sketch is given of Taylor’s dislocation density-based model description, leading to the prediction of a parabolic, tensile, stress–strain curve for the plastic deformation of aluminum.

Plastic-embedded protein crystals [PDF]
Journal of Synchrotron Radiation, 2006 Rapid vitrification followed by the replacement of the vitrified water by a solvent (freeze substitution) and then resin is a widely used procedure for preparing biological samples for electron microscopy. The resulting plastic-embedded samples permit convenient room-temperature sectioning (microtomy) and can yield well preserved cellular structures ...
