Dynamic Similitude of Human Head SurrogatesMultiscale Science and Engineering - - 2024
Arthur Koster, Ashfaq Adnan
Due to the highly transient nature of head injury events that lead to traumatic brain injury (TBI) and the complexity of the human head, a structural-dynamics-informed design process is needed to augment research efforts that utilize human head surrogate models. Such models are capable of accurately mimicking the response of biological systems and allow for models that explore biological differenc...... hiện toàn bộ
A Short Review of the Literature on the Multiscale Modeling of Nanoparticle-Reinforced CompositesMultiscale Science and Engineering - Tập 4 - Trang 94-101 - 2022
Jinho Bang, Jin-Ho Bae, Jongwon Jung, Beomjoo Yang
In recent years, various nanocomposites based on the inherent properties of nanofillers have been actively investigated. When nanoparticles are incorporated into a polymeric matrix, such as nylon, polyurethane, or polypropylene, lightweight composites with excellent strength can be fabricated. Given the rapid developments in nanotechnology, nanocomposites with enhanced performance are expected to ...... hiện toàn bộ
A Brief Overview of Delamination Localization in Laminated CompositesMultiscale Science and Engineering - Tập 4 - Trang 102-110 - 2022
Asif Khan, Heung Soo Kim
Inter-ply separation or delamination is a commonly occurring phenomenon in laminated composites that results in substantial loss of structural stiffness and strength without noticeable effects on the surface of the material. This article reviewed different approaches of delamination detection and localization ranging from physical based methods to the recent artificial intelligence-based algorithm...... hiện toàn bộ
Discrete Element Method of the Dynamic Behavior of Flaky Particles Using the Rigid Plate ModelMultiscale Science and Engineering - Tập 2 - Trang 63-68 - 2020
Seungwoo Lee, Junyoung Park
The discrete element method (DEM) can be used to simulate the behavior of spherical particles. The spherical particles are regarded as rigid bodies in the calculation of DEM. However, the properties of these spherical particles are not applicable to powders consisting of plate-shaped or flaky particles because of the lack of geometrical consideration. Inevitably, the lack of geometrical considerat...... hiện toàn bộ
Microstructural Evolution of Superelasticity in Shape Memory AlloysMultiscale Science and Engineering - Tập 1 - Trang 141-149 - 2019
Min-Jyun Lai, Hung-Yuan Lu, Nien-Ti Tsou
Superelasticity in shape memory alloys (SMAs) is an important feature which caused by martensitic transformation and microstructural evolution. The composition of crystal variants and microstructures during the superelasticity process are simulated by molecular dynamics in the current work. Then, a computational post-processing scheme, which can identify variants type and interface orientation are...... hiện toàn bộ
