On the Characterization of Engineered Elastomers At High Strain Rates
… under dynamic loading. For this purpose, a Kolsky Bar was designed and constructed to test soft, flexible materials. The third aspect of the work dealt with the numerical modelling of the developed testing apparatus. Finite element methodology was used to optimize the testing parameters and …

High Strain-Rate Responses of Mechanical Metamaterials
… uniaxial compression and custom microscale Kolsky bar capabilities, we uncover the strain rate dependence of mechanical metamaterials over eight orders of magnitude, ranging from strain rates of 10^−3 to 10^5 s^−1. Herein, we describe the development and execution of direct impact …

Experimental Techniques for Shear Testing of Thin Sheet Metals and Compression Testing at Intermediate Strain Rates
… using a servo-hydraulic load frame and tension Kolsky bar, respectively. Specimens are fabricated from a 0.5in Al2024-T351 plate with their gage sections orientated in various directions. Tests are conducted at shear strain rates ranging from 0.01(1/s) to 9000(1/s). Traditionally, shear …

Structural Evolution in the Dynamic Plasticity of FCC Metals
… the study: Instron and split Hopkinson pressure bar methods. Both methods are well established, and cover the majority of the range of rates under study. Emphasis is made on minimising experimental sources of error, and subsequently accounting for those which are unavoidable. Finally, the …

Additively Manufactured Metallic Cellular Materials for Blast and Impact Mitigation
Selective laser melting (SLM) is an additive manufacturing process which enables the creation of intricate components from high performance alloys. This facilitates the design and fabrication of new cellular materials for blast and impact mitigation, where the performance is heavily influenced by …
