Elastic immersive experimentation: theory and physical implementation

open access: yes, 2021
Mechanical wave propagation offers one of the most reliable ways to understand and characterize natural and synthetic materials which only offer limited accessibility, or which for other reasons can not be probed directly. Thus, an ever increasing understanding of elastic wave propagation phenomena in such real earth materials and media is essential to

The Nonlinear Visco‐Hyperelastic Damage Mechanics of Individual Electrospun Polycaprolactone Fibers: Experiments and Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Analysis of surface polariton resonance for nanoparticles in elastic system [PDF]

open access: yesarXiv, 2018
This paper is concerned with the analysis of surface polariton resonance for nanoparticles in linear elasticity. With the presence of nanoparticles, we first derive the perturbed displacement field associated to a given elastic source field. It is shown that the leading-order term of the perturbed elastic wave field is determined by the Neumann-Poinc ...

Profilometry‐Based Indentation Plastometry Testing of Tungsten at High Temperature

open access: yesAdvanced Engineering Materials, EarlyView.
Profilometry‐based indentation plastometry (PIP) allows extraction of stress‐strain curves from indent profiles. Tungsten is of industrial interest but is brittle at room temperature. It does plastically deform at higher temperatures. Excellent agreement is obtained between the two techniques in this regime, but PIP also gives plasticity ...

Exploration of Structure-Property Relationships

open access: yesCHIMIA, 2001
Electrostriction and elasticity provide highly sensitive probes for the exploration of structure-property relationships. With the aid of modern high-resolution capacitive dilatometers reliable linear and quadratic electrostrictive constants can ...

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...
