Phase field modeling of dynamic brittle fracture at finite strains
… field model used for dynamic brittle fracture at finite strains. Subsequently, this model is implemented into the in-house finite element software SESKA to solve the benchmark tension and shear tests on a single-edge notched block. The implementation adopts the so-called monolithic scheme, which …

Single-crystal plasticity at finite strains: a computational investigation of hardening relations
… describe single-crystal viscoplasticity under finite strains. The second objective is to use the computer code that is developed to examine three hardening laws that have been proposed. The first is an isotropic hardening law. The second is a hardening law that is expressed implicitly. The …

Identification of Fold Hinge Migration in Natural Deformation: A New Technique Using Grain Shape Fabric Analysis
Partitioning of finite strains in different domains within the limb and hinge regions of a fold can be used to understand the deformation processes operative during fold formation. Samples taken from the limb and hinge regions of a gently plunging, asymmetric, tight, mesoscale fold in the Erwin …

Biaxial Mechanical Behavior of Swine Pelvic Floor Ligaments: Experiments and Modeling
… revealed that the ligaments undergo large strains and are anisotropic. The direction normal to the upper vagina was typically stiffer than the transverse direction. Stress relaxation tests showed that the relaxation was the same in both directions, and that more relaxation occurred when the …

Stable algorithms for generalized thermoelasticity based on operator-splitting and time-discontinuous Galerkin finite element methods
… and the time-discontinuous Galerkin finite element method for the non-classical, linear thermoelastic model. The coupled problem is split into two contractive sub-problems, namely, the mechanical phase and thermal phase, on the basis of an entropy controlling mechanism. In the …

Modeling curvature-resisting material surfaces using isogeometric analysis
… of curvature-dependent surface energetics at finite strains using surface-enriched isogeometric analysis. Coupled with a hyperelastic bulk, bending-resistance of material surfaces furnishes a new physical length scale, i.e., the elastobending length. We quantify the effect of elastobending …

Multiscale phase-field approach to martensitic phase transformations that satisfies lattice instability conditions
… to martensitic phase transformations (PTs) at finite strains are developed at nanoscale that satisfies crystal lattice instability conditions obtained by atomistic simulations. Theory includes a fully geometrically nonlinear formulation for the general case of finite elastic and …

Instability of Dielectric Elastomer Actuators
… and energy harvesters. Soft dielectrics undergo finite strains, and their modelling requires a formulation based on the Mechanics of Solids at large deformations. A major problem that limits the widespread diffusion of such devices in everyday technology is the high voltage required to activate …

Modeling phase transformations in single and polycrystalline aggregate and grain growth
… scale-free phase-field approach, augmented by finite element method simulations, to investigate multivariant martensitic phase transformations in crystalline aggregates. Central to our exploration is a model meticulously developed to scrutinize phase transformation behaviors and microstructural …

A variational multiscale computational framework for nonlinear interfacial solid mechanics
… whereby the coarse scales represented on the finite element mesh are unable to resolve the fine-scale features of the solution, and failure to account for the fine scales manifests instabilities in the computed results. In the case of interfaces, the source of instability is the discontinuity …
