Dynamic material property characterization by using split Hopkinson pressure bar (SHPB) technique
Nuclear Engineering and Design, 2003Abstract Mechanical properties of the materials used for nuclear power plants, transportations and industrial machinery under high strain rate loading conditions such as seismic loading are required to provide appropriate safety assessment to these mechanical structures.

Abstract Adhesive joining became a common manufacturing technique for joining materials, particularly in the automobile and aerospace industries. However, only recently the scientific community started to study the mechanical behavior of bonded joints, having in mind impacts and high strain-rate solicitations.

Dynamic Behaviour of Pre-Strained and Baked Steels Using Split Hopkinson Pressure Bar (SHPB)
SAE Technical Paper Series, 2006<div class="htmlview paragraph">A Split Hopkinson Pressure Bar (SHPB) was used to obtain dynamic behaviour of various steels at large strains and high strain rate. The dynamic loading response was compared between mild steels and cold rolled high strength steels, Dual Phase 590 and TRIP 780. Only sheet samples were available for the high strength

The split Hopkinson pressure bar (SHPB) has been widely used to determine the mechanical properties of materials at high loading rates. However, to ensure test reliability, the source of measurement error must be identified and eliminated. During the experiment, specimens were placed between the incident and the transmit bar.

Recent Advancements in Split Hopkinson Pressure Bar (SHPB) Technique for Small Strain Measurements
2008Recent advances in SHPB technique are discussed. A compliance calibration technique together with an exact 1-D Hopkinson bar theory has been developed to accurately measure the rate dependent elastic modulus in the small strain range. A right circular cylinder (RCC) specimen with chamfered edges is found to minimize the stress concentration at the ...

The aluminum 7075-T6 is known as an alloy widely used in aircraft structural applications, which does not exhibit strain rate sensitivity during dynamic compressive tests. Despite mechanical importance of the material, there is not enough attention to determine appropriate sample dimensions such as a sample diameter relative to the device bar diameter ...

Dynamic mechanical behavior of geomaterials has been widely observed in tunneling, oil and gas extraction, and blasting in civil and mining applications. It is important to understand how much energy is necessary to break or fail geomaterials to optimize the design of blasting patterns, oil and gas extractions, demolition, military defense, etc ...

Abstract This work emphasizes obtaining and validating experimental test results of ultra-high performance concrete (UHPC) under compressive impact loading at high strain rates (30–200 S−1). Cylindrical specimens of 9.2 mm in height and 23.8 mm in diameter were used for compression tests under dynamic and static conditions.
