TL;DR: The results of simplified numerical models, carried out using Ansys/AutoDYN, are validated with experiments for deflection. as mentioned in this paper showed that smaller inclusive angles deflect more blast energy resulting in lower mid-point plate deflection, while the measured impulse does not significantly change, an increase in midpoint deflection is observed with a decrease in stand-off distance for a constant mass of explosive.

TL;DR: In this paper, a Timoshenko model of transverse piezoelectric beam vibration is developed to address the limitations of the Euler-Bernoulli model for high frequencies accurately.
Abstract: Piezoelectric bimorph cantilevered beams are often used as energy harvesting devices. These devices are desired for, among other applications, remote sensing and animal tracking due to their potential for eliminating the need for battery replacement. Existing models of piezoelectric bimorph cantilevered beams have proved to describe the dynamics of slender beams at high frequencies accurately. In this paper, a Timoshenko model of transverse piezoelectric beam vibration is developed to address these limitations. Exact expressions for the voltage, current, power, and tip deflection of the piezoelectric beam are derived. Subsequently, several case studies are presented that examine the frequency response of vibration-based energy harvesters using this model. It is shown that the predicted responses converge towards previously derived Euler–Bernoulli beam models under certain limiting conditions. The Timoshenko model shows that the Euler–Bernoulli model severely over-predicts the tip displacement and consequently the power transduction of a cantilevered piezoelectric bimorph at low length-to-width aspect ratios.

TL;DR: An overview of photothermal deflection principles and applications is given, and three configurations usually employed are compared and their respective advantages are discussed in relation to their application.
Abstract: An overview of photothermal deflection principles and applications is given. The modeling of temperature distribution and the calculation of deflection that is due to both the refractive-index gradient and the thermal deformation of the sample are presented. Three configurations usually employed are compared, and their respective advantages are discussed in relation to their application. The calibration for absolute measurement of absorption is detailed, showing that calibration limits the accuracy of measurement. Some examples of specific information obtained by photothermal mapping of absorption are given.
