Lubricants, 2021 When an elastomer approaches or retracts from an adhesive indenter, the elastomer’s surface can suddenly become unstable and reshape itself quasi-discontinuously, e.g., when small-scale asperities jump into or snap out of contact. Such dynamics lead to a

The peeling strength analysis of sandwich structure with cohesive element model [PDF]
ITM Web of Conferences, 2022 In this study, cohesive element models are applied to the strength analysis of the sandwich structure. As the sandwich structures have been used increasingly in the field of automotive light-weighting, the strength analysis of the sandwich structures ...

Crack nucleation in circular disk under mixed boundary conditions
Archives of Mechanics, 2015 A model of crack nucleation in a circular disk, based on consideration of cracking process zone is suggested. It is assumed that the cracking process zone is a finitelength layer containing a material with partially disturbed bonds between separate ...

An isogeometric approach to cohesive zone modeling [PDF]
International Journal for Numerical Methods in Engineering, 2010 AbstractThe possibility of enhancing a B‐spline basis with discontinuities by means of knot insertion makes isogeometric finite elements a suitable candidate for modeling discrete cracks. In this contribution we use isogeometric finite elements to discretize the cohesive zone formulation for failure in materials. In the case of a pre‐defined interface,

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Regularized Interface Model for Simulating the Response of Adhesive Joints
Annals of "Dunarea de Jos" University of Galati, Fascicle XII, Welding Equipment and TechnologyA regularized interface damage model is presented grounded on the cohesive-zone concept. This is obtained using a gradient-based formulation, which is equivalent to the introduction of the laplacian of a scalar damage field into the threshold function of

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
