Porosity of the free boundary for singular p-parabolic obstacle problems
Electronic Journal of Differential Equations, 2015 In this article we establish the exact growth of the solution to the singular quasilinear p-parabolic obstacle problem near the free boundary from which follows its porosity.

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.

An Interpolating Boundary Element-Free Method for Signorini problems
四川大学学报. 自然科学版, 2016 Combining the improved interpolating moving least-square (IIMLS) method and boundary integral equations (BIEs), a novel boundary-only meshless method, the interpolating boundary element-free method (IBEFM), is developed for the numerical solution of ...

Displacement of oil by water in a single elastic capillary
Boundary Value Problems, 2017 In this paper we consider the evolution of a free boundary separating two immiscible viscous fluids with different constant densities. The joint motion of liquids in the solid skeleton is described by Stokes equations coupled with Lamé equations, driven ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Qualitative behavior of axial-symmetric solutions of elliptic free boundary problems
Electronic Journal of Differential Equations, 1997 axial-symmetric solutions and qualitative geometric properties of the free boundary are compared to those of the fixed boundary for the axial and radial directions. Counterexamples obtained previously by the first author show that our results cannot hold

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 ...

Perturbation formula for the two-phase membrane problem
Advances in Difference Equations, 2011 A perturbation formula for the two-phase membrane problem is considered. We perturb the data in the right-hand side of the two-phase equation. The stability of the solution and the free boundary with respect to perturbation in the coefficients and ...
