Reinhard Pfriem,Christian Lehmannith theoretical predictions and with other experimental values obtained using a laser displacement transducer and accelerometers. Due to their high accuracy, small dimensions, low weight, easy usage, and low cost, piezoelectric disks seem to be an attractive tool for experimental modal analysis of engineering structures.

Volker M. Brennecke,Frank Plümacher as 400 MPa resulted in multiple fractures not originating from a single flaw. Under tension the spallation strength of zeolite was measured as 215 MPa with transgranular fracture observed as the dominant spallation feature, further indicating the brittle failure at high strain-rates.

Statistical Characterizations for Tensile Properties of Co-polymer Aramid Fibers: Loading Rate Effeballistic impact are rarely reported. In this study, we measure single fiber tensile properties at high rate loading conditions by clamping a fiber to the grips of a mini Kolsky bar, and investigate their statistical distributions as well as fiber morphologies.

Longitudinal Wave Propagation Including High Frequency Component in Viscoelastic Bars,xperiments using the ultrasonic transducers in the high frequency area from 20 to 200 kHz. Consequently, it was found that the second-mode vibration as well as the first-mode should be considered in the high frequency area. It was also confirmed that the second-mode vibration influenced deeply as the radial thickness became thin.
