Revisiting Safe Temperature for Environmental Accelerated Aging of Additively Manufactured Polymers
Kevin LoGiudice, Keven Alkhoury, Nikash Long +5
Accelerated aging is widely used to study the long-term behavior of materials within laboratory time scales, particularly for materials exposed to solvent environments over extende…
Modeling damage and fracture in additively manufactured polymeric triply periodic minimal surface lattices
Abhishek Gupta, Aditya Konale, Ke Ma +4
Architected triply periodic minimal surface (TPMS) lattices offer superior specific energy absorption, toughness, fatigue strength, and tunability. While recent advancements have e…
A non-local constitutive model for the Mullins effect in filled elastomers
Keven Alkhoury
Filled rubber-like materials are widely used in engineering applications and are well known to exhibit the Mullins effect. In this work, an established local constitutive model fro…
A finite element implementation of a large deformation gradient-damage theory for fracture with Abaqus user material subroutines
Keven Alkhoury, Shawn A. Chester, Vikas Srivastava
Recent advancements in computations have enabled the application of various modeling approaches to predict fracture and failure, such as the gradient-damage (phasefield) method. Se…
