Impact Behavior of Recycled Aggregate Concrete Based on Split Hopkinson Pressure Bar Tests

open access: yesAdvances in Materials Science and Engineering, 2013
This paper presents the experimental results of recycled aggregate concrete (RAC) specimens prepared with five different amounts of recycled coarse aggregate (RCA) (i.e., 0, 25%, 50%, 75%, and 100%) subjected to impact loading based on split Hopkinson ...

Pandemic Geographies of Home: Domestic Thresholding in Response to COVID‐19

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
Short Abstract With the home at the forefront of political and public health responses to COVID‐19, the thresholds between domestic space and the world beyond acquired a new significance in people's everyday lives. This paper introduces the concept of ‘thresholding’ to explore the ways in which internal and external thresholds are understood and ...

Effect of structurally-induced lateral confinement on split Hopkinson pressure bar test specimens of concrete-like materials

open access: yesEPJ Web of Conferences, 2015
In dynamic testing of concrete-like materials, there is a need in distinguishing structural effects from genuine strain-rate effects. In this paper, this generic problem is studied by numerical simulations based on a phenomenological material model ...

Numerical Simulation for Bar Straightness Effect in Split Hopkinson Pressure Bar

open access: yesProcedia Engineering, 2017
Abstract Bars alignment in a Split Hopkinson Pressure Bar influences the quality of signal recorded during experiments, and thus affects the data of material properties being measured. There are some parameters directly related to the bars alignment such as their straightness, the impact face parallelism, and the neutral axis offset.

Split Hopkinson pressure bar measurements of polymer energy dissipation and identification of the glass transition condition

open access: yes
We explore the idea of using a split Hopkinson pressure bar to measure polymer energy dissipation. For an elastic specimen the sum of the mechanical energies within the transmitted and reflected pressure waves ought to be equal to mechanical energy in ...

Dynamic Increase Factors for High Performance Concrete in Compression using Split Hopkinson Pressure Bar [PDF]

open access: yes, 2007
This paper provides dynamic increase factors (DIF) in compression for two different High Performance Concretes (HPC), 100 MPa and 160 MPa, respectively. In the experimental investigation 2 different Split Hopkinson Pressure Bars are used in order to test

Experimental Work for Bar Straightness Effect Evaluation of Split Hopkinson Pressure Bar

open access: yes, 2021
Bar straightness is one of several factors that can affect the quality of the strain wave signal in a Split Hopkinson Pressure Bar (SHPB). Recently, it was found that the bar components of the SHPB at the Lightweight Structures Laboratory displayed a ...
