Editorial

Editorial by Gurumurthy Kalyanaram Partnership with Indian Society for Applied Mechanics (ISAM) I am delighted that the prestigious Indian Society for Applied Mechanics (ISAM) has partnered with the Journal of Engineering and Technology Review for publication of very impactful research manuscripts. As you will note, these papers are thoughtful and insightful, contributing not only to Read More …

Parametrization and model validation for metal using J2 Plasticity and digital image correlation

Abstract Convenonally, the parameters of elasto-plasc material models are calibrated using experiments that develop homogeneous strain/stress fields, while the model is then used in applicaons where the responses are heterogeneous in nature depending on the structural geometry and/or nature of loading. This entails that the local response predicted by a considered model should also be Read More …

Simulations and experiments on an energy harvester under harmonic excitations

Abstract Vibraon energy harvester consists of a structural member such as a beam, plate or a combinaon of different members wherein the structural members are bonded with one or more patches or layers of piezo-electric transducers. This structural member bonded with piezo-electric patches can convert the base vibraon into electrical energy. This technique is becoming Read More …

Predicting the Rotational Compliance of a Flight Inter-section Joint

Abstract Flight intersecon joints are temporary joints used to integrate one airframe secon with another. They are characterized by their inherent capacity to resist the rotaonal flexibility when subjected to an external bending moment, commonly termed as the joint rotaonal compliance (JRC). They are quanfied mostly by extensive experiments. This paper presents the details of Read More …

Estimation of Piezo-electric Transducer parameters in a dynamic fluid domain

Abstract In an underwater sensor array system, various types of piezo-electric transducers are used for generang and receiving acousc waves. To generate acousc waves underwater, sonar systems predominantly use PZT based electro-acousc transducers in the form of arrays housed inside a sonar dome. The transducers and thus the arrays in the system have their frequency Read More …
