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

Numerical Simulation for Bar Straightness Effect in Split Hopkinson Pressure Bar
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.

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