Flow Stress of beryllium: Attempt for a Bayesian Crossed-data Analysis from Hopkinson Bars to Rayleigh-Taylor Instabilities

open access: yesEPJ Web of Conferences, 2018
In this paper, we demonstrate by a Bayesian approach the incapacity of the Preston-Tonks-Wallace (PTW) strength model to represent, with the same set of parameters, the flow stress of beryllium in both moder-ate and highly dynamic experiments, and ...

Tensile Split Hopkinson Bar Technique: Numerical Analysis of the Problem of Wave Disturbance and Specimen Geometry Selection

open access: yesMetrology and Measurement Systems, 2016
A method of tensile testing of materials in dynamic conditions based on a slightly modified compressive split Hopkinson bar system using a shoulder is described in this paper.

Combined shear/tension testing of fibre composites at high strain rates using an image-based inertial impact test

open access: yesEPJ Web of Conferences, 2018
Testing fibre composites off-axis has been used extensively to explore shear/tension coupling effects. However, off-axis testing at strain rates above 500 s-1 is challenging with a split Hopkinson bar apparatus.

Numerical Simulation on the specimen dynamic plastic deformation behaviour in the torsional split Hopkinson bar test

open access: yesEPJ Web of Conferences, 2018
The torsional split Hopkinson bar (SHB) is an important method to study the dynamic shear behaviour and shear localization of materials under high strain rates. Different specimen sizes were used in literatures, and the size of the specimen might have an

Laboratory Investigation of Energy Propagation and Scattering Characteristics in Cylindrical Rock Specimens

open access: yesAdvances in Civil Engineering, 2018
Deep mining involves complex geological environments. Moreover, along with strong disturbance, rockbursts and other severe dynamic hazards can occur frequently.

Optimization of Optical and Mechanical Properties of Real Architecture for 3-Dimensional Tissue Equivalents: Towards Treatment of Limbal Epithelial Stem Cell Deficiency [PDF]

open access: yes, 2015
Limbal epithelial stem cell (LESC) deficiency can cause blindness. Transplantation of cultured human limbal epithelial cells (hLE) on human amniotic membrane (HAM) can restore vision but clinical graft manufacture can be unreliable.

Dynamic behavior and microstructural properties of cancellous bone

open access: yes, 2009
The aim of the presented study is to identify some properties of the dynamic behavior of the cancellous bone and to identify the link between this mechanical behavior and the microstructural properties.
