Cohesive Zone Damage-Healing Model for Self-Healing

A cohesive zone damage-healing model (CZDHM) derived based on the laws of thermodynamics for self-healing materials is presented. The well-known nominal, healing, and effective configurations of classical continuum damage mechanics are extended to self-healing materials. A new physically-based internal crack healing state variable is proposed for describing the healing evolution within the

Adhesion

Both adhesion (including the transition zone) and cohesion play their part in maximizing the strength of a bond. Just as with a chain, the weakest link in a bonded joint determines what loads the joint can be subjected to. The cohesive properties of an adhesive are already determined by the manufacturer.

Comparison of FEM-Based 3-D Dynamic Fracturing Simulations

May 10, 2022 · In this paper, by introducing a so-called "extrinsic cohesive zone model (ECZM)", which adaptively inserts the CEs, we compared the results of 3-D dynamic fracturing simulations by the ICZM and ECZM using the experimental data obtained from the dynamic spalling test for rocks. Using the same Young's modulus, Poisson's ratio, density and

Dynamic Seal at the Aortic Neck-Endograft Interface

The seal zone in our simulations is fully dynamic and modeled using the cohesive zone method. Our methodology allows full separation of the aorta and endograft, simulating loss of seal and endoleak. Results: Using patient-specific geometry, we show that our approach is capable of predicting the location of rupture in an index patient who presented with a ruptured juxtarenal aneurysm.

A Rate-Dependent Cohesive Zone Model for Adhesively Bonded

Apr 02, 2022· The parameters for the implemented cohesive zone model are found directly by evaluation of experimental data. The comparison of simulations with experimental results for different specimen types and test velocities validates the proposed model. The critical energy release rate of adhesively bonded joints is usually measured in (tapered) double

CiteSeerX — MIXED-MODE COHESIVE-ZONE MODELS FOR

Abstract. Cohesive-zone models for interfaces incorporate both strength and energy parameters. There-fore, they provide a natural bridge between strength-based models and energy-based models for fracture, allowing delamination to be described by a single framework that covers a range of applications for which the strength or energy criteria alone might not be sufficient.

Cohesive zone length of metagabbro at supershear rupture

We picked up the peak strain and zero-crossing strain locations to measure the cohesive zone length. By compiling the stick-slip event data, the cohesive zone length is about 50 mm although it scattered among the events. We could not see any systematic variation at the location but some dependence on the rupture velocity.

Thermomechanical Failure Analysis of Through-Silicon Via

02-05-2022 · Abstract: An analytical approach to predict initiation and growth of interfacial delamination in the through-silicon via structure is developed by combining a cohesive zone model with a shear-lag model. Two critical temperatures are predicted for damage initiation and fracture initiation, respectively. It is found that via extrusion significantly increases beyond the second critical temperature.
