Design of a split Hopkinson pressure bar with partial lateral confinement [PDF]
This paper presents the design of a modified split Hopkinson pressure bar (SHPB) where partial lateral con-\ud finement of the specimen is provided by the inertia of a fluid annulus contained in a long steel reservoir. In\ud contrast to unconfined testing, or a constant cell pressure applied before axial loading, lateral restraint is permitted\ud to ...

Abstract Lateral erosion of salt marshes via cliff retreat is a primary cause of global marsh loss, driven by interactions between hydrodynamics, sediment, and vegetation. While previous studies show a linear relationship between wave power and cliff retreat, models based on this relationship are largely unvalidated for short‐term (sub‐yearly) and ...

Signal Correction for the Split-Hopkinson Bar Testing of Soft Materials
The Split-Hopkinson pressure bar (SHPB) test is a commonly accepted experiment to investigate the material behavior under high strain rates. Due to the low impedance of soft materials, here, the test has to be performed with plastic bars instead of metal

Abstract During an earthquake a dynamic rupture propagates, causing fractures and permanent damage that modify the mechanical properties of the fault and its surroundings. Reciprocally, the energy dissipated by the mechanical transformation of the fault rock has a direct feedback on the dynamics of the seismic rupture.

Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.

Compressive split Hopkinson pressure bar testing
In this era, static mechanical properties such as hardness and strength can usually be found easily from various sources online. However, most of such sources do not provide certain mechanical properties of a material such as strain rate dependant data ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

A NOTE ON DATA PROCESSING IN THE SPLIT HOPKINSON PRESSURE BAR TESTS [PDF]
In this paper, a close-form relationship between the incident wave and the transmitted wave was deduced on the analysis of elastic wave propagation in SHPB tests for the elastic specimen. The relationship was applied to determine the time delay in data processing of SHPB tests in order to improve the accuracy of the measured stress-strain curve in the ...
