Hydrostatic compression on polypropylene foam [PDF]

, 2014
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to ...

A Study of Static and Dynamic Mechanical Behavior of the Substrate in Ultrasonic Consolidation [PDF]

, 2006
A new 2-D FEM model is developed for a fundamental study of the time dependent mechanical behavior of the substrate in ultrasonic consolidation. The simulation shows that for a given vibration condition, the amplitude of contact friction stress and ...

Bone Stress-Strain State Evaluation Using CT Based FEM

Frontiers in Mechanical Engineering, 2021
Nowadays, the use of a digital prototype in numerical modeling is one of the main approaches to calculating the elements of an inhomogeneous structure under the influence of external forces. The article considers a finite element analysis method based on

High-temperature mechanical behavior of polycrystalline yttrium-doped barium cerate perovskite [PDF]

, 2011
The high-temperature mechanical properties of the mixed ionic-electronic conductor perovskite BaCe0.95Y0.05O3-δ with average grain size of 0.40μm have been studied in compression between 1100 and 1300°C in air at different initial strain rates.

Evidence for realignment of the charge density wave state in ErTe$_3$ and TmTe$_3$ under uniaxial stress via elastocaloric and elastoresistivity measurements

, 2022
We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides ($R$Te$_3$ for $R$=Er,Tm) as a function of in-plane uniaxial stress.
