Mechanisms of the improved stiffness of flexible polymers under impact loading

Nanotechnology Reviews, 2022
The flexible polymers have an outstanding impact-resistant performance because of the improved stiffness upon a high speed loading. At the aspect of microstructure, the soft segments make an important contribution.

Controllable branching of robust response patterns in nonlinear mechanical resonators

Nature Communications, 2023
Feedback control applied to mechanical resonators can lead to the formation of various complex dynamic behaviors. Here the authors demonstrate flexible and controllable switching between dynamical structures in the response of harmonically driven micro ...

Mechanical response of a lined pipe under dynamic impact [PDF]

Engineering Failure Analysis, 2018
Abstract An experimental and numerical investigation on the mechanical response of a lined pipe (compound pipe) under a dynamic impact is presented. The influence of the impact energy has been studied in terms of the depth of the dent formed, and of the strains and residual stresses. To this end, a three-dimensional explicit dynamic non-linear finite

Nonlinear vibration of thick FGM plates on elastic foundation subjected to thermal and mechanical loads using the first-order shear deformation plate theory

Cogent Engineering, 2015
This paper presents an analytical approach to investigate the nonlinear dynamic response and vibration of thick functionally graded material (FGM) plates using both of the first-order shear deformation plate theory and stress function with full motion ...

Dynamics in Responsible Behaviour In Search of Mechanisms for Coping with Responsibility

Journal of Business Ethics, 2003
In this article the authors focus on the emergence, or disappearance, of notions of responsibility in social dynamic processes. Hence, the starting point in this article is concrete behavior within organisational settings. This article presents a systematic overview of mechanisms related to acting upon a sense of moral responsibility.

Dynamic Fibroblast Cultures [PDF]

Cell Adhesion & Migration, 2007
Mechanical forces play an important role in the organization, growth and function of tissues. Dynamic extracellular environment affects cellular behavior modifying their orientation and their cytoskeleton. In this work, human fibroblasts have been subjected for three hours to increasing substrate deformations (1-25%) applied as cyclic uniaxial ...

Molecular Dynamics Simulations of Deformation Mechanisms in the Mechanical Response of Nanoporous Gold [PDF]

Materials, 2020
The mechanical behaviour of nanoporous gold has so far been the subject of studies for bicontinuous morphologies, while the load transfer between ligaments is the primary challenge for using nanoporous structures—especially membranes with nanopores—in single-molecule sensors.

Comparative Study on Mechanical Response in Rigid Pavement Structures of Static and Dynamic Finite Element Models

Aerospace
The safety of airport runways is important to guarantee aircraft taking-off, landing, and taxiing, and the comparison of the mechanical response of pavement structures under dynamic and static loading by LS-DYNA has rarely been studied.
