This paper presents the results of study dynamic impact behaviour AA2124-SiC Metal Matrix Composite (MMC) material with different particle reinforcement sizes and qualities using a compressive Split-Hopkinson Pressure Bar (SHPB) apparatus. Mechanical tests were performed at strain rates 1000 s?1, 2000 3000 s?1 temperatures room temperature (25 °C), 100 °C 200 °C. Microstructural analyses carrie...

Marine, aerospace, ground and civil structures can receive unexpected loading thatmay compromise integrity during their life span. Therefore, improvement in detectingdamage can save revenue and lives depending upon the application. The prognosticcapability is usually a function of the examiner’s experience, background and datacollection during the evaluation. Nondestructive eval...

Nanofillers can be added to polymers improve their mechanical behaviour. However, the yield behaviour of most polymer composites is influenced by strain rate. The majority research focused on at high rates. This work aims investigate how hydroxyapatite (HAP) and reduced Graphene Oxide (rGO) nanofillers affect properties sulphonated polyetheretherketone (sPEEK) low (tensile compression behaviour...

The mechanical behavior of Zr41.25Ti13.75Cu12.5Ni10Be22.5 LM-1 has been extensively characterized under quasistatic loading conditions; however, its mechanical behavior under dynamic loading conditions is currently not well understood. A Split–Hopkinson pressure bar SHPB and a single-stage gas gun are employed to characterize the mechanical behavior of LM-1 in the strain-rate regime of 102–105 ...
