ROS‐Scavenging Multifunctional Microneedle Patch Facilitating Wound Healing

Advanced Healthcare Materials, Volume 14, Issue 31, December 8, 2025.
A reactive oxygen species (ROS) scavenging and immunomodulatory microneedle patch based on hyaluronic acid methacrylate (HaMA) and Flightless I (Flii)‐siRNA‐laden arginine functionalized poly (β‐amino ester)/alginate particles is developed for chronic wound healing applications.

Fatigue crack propagation analysis using the GTN damage model

, 2021
Fatigue is one of the most prominent mechanisms of failure. Thus, its evaluation is of prime order in engineering components subjected to cyclic loads. The fatigue crack growth process is usually accessed through the stress intensity factor, ΔK. In accordance, the fatigue crack growth rate is, typically, defined by the da/dN- ΔK curves.

Implementation of the GTN Damage Model to Simulate the Small Punch Test on Pre-Cracked Specimens

Procedia Engineering, 2011
Nowadays, pre-cracked Small Punch Tests (P-SPT) are used in those cases where there is not enough material for conducting conventional tests. In this paper, P-SPT has been used to determine the fracture properties of the 15.5PH steel, using the micromechanical model, developed by Gurson-Tvergaard-Needleman (GTN).

A new implementation of the anisotropic plasticity–ductile damage model coupling Hill yield and GTN failure criteria in Abaqus UMAT: Identification of parameters for AA6022

Applications in Engineering Science
This paper adopts a 2D implementation of an anisotropic plasticity–ductile damage model coupling Hill yield and GTN failure criteria and extends it to a 3D implementation in a user material subroutine (UMAT) of Abaqus software.

Extending GTN model to viscoplasticity for describing ductile damage in irradiated F/M steels

Engineering Fracture Mechanics
Irradiation of Eurofer97, a reduced activation ferritic/martensitic steel used in fusion reactor applications, induces significant hardening, loss of uniform elongation (UE) and embrittlement. To estimate the maximum operating strain range of irradiated components beyond the loss of UE, a coupled deformation-ductile damage model at the component scale ...
