Design and Simulation of Insert to Measure Dynamic Sliding Friction in a Split-Hopkinson Pressure Bar [PDF]
Interfacial friction is a key aspect to understanding and modelling dynamic processes in which materials interact. However, friction is a complex phenomenon that depends on a multitude of factors, including sliding velocity.

The split Hopkinson bar bulge setup: a novel dynamic biaxial test method [PDF]
In sheet metal forming, very often, large plastic deformations are imposed to a thin plate. An accurate description of the material’s elastoplastic response is therefore of paramount importance to perform finite element (FE) simulations of an actual ...

A Laboratory-Scale Instrumented Forging Hammer as an Intermediate Strain Rate Testing Device [PDF]
Mechanical characterisation of metallic materials at intermediate strain rates is essential to calibrate and validate computational models for industrial applications such as high-speed forming processes i.e. hammer forging, blanking, forming, etc.

The Direct Impact Method for Studying Dynamic Behavior of Viscoplastic Materials [PDF]
This work is devoted to the direct impact method for determining the deformation diagrams of viscoplastic materials at high strain rates. As the conventional Split Hopkinson Pressure Bar method, the direct impact method is based on the measuring bar ...

Behavior of high-density polyethylene at high strain rates
The Hopkinson split pressure bar (HSPB) was used for the testing of three polymers at strain rates between 10^2 to 10^3 1/s. Higher strain rates were achieved using the direct Hopkinson test.

Correction Procedure of Wave Signals for a Viscoelastic Split Hopkinson Pressure Bar [PDF]
A polymeric split Hopkinson pressure bar technique (SHPB) is preferred for testing materials with low mechanical impedance. However, the use of polymeric bars requires additional analysis for data reduction, temperature complications and additional ...
