NMIMS Engineering and Technology Review

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 …

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 …

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 …

Abstract The corrugated core sandwich structure is being considered for the Integrated Thermal Protecon System (ITPS) of Reusable Launch Vehicles (RLVs) since it is thermally insulave and has a beer specific loadcarrying capability than convenonal TPS. However, the analyses of the RLVs components such as wings, fuselage, etc., along with the ITPS panel may become Read More …

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 …

Abstract Quality control is an essenal operaon of the pharmaceucal industry. Drugs must be marketed as safe and therapeucally acve formulaons whose performance is consistent and predictable. It not only protects the manufacturer against compensaon claims but also guarantees the paent a safe and effecve product. In this work official, an inline quality test for Read More …

Abstract Lap joints fastened by countersunk screws are commonly adopted in many engineering applicaons wherein the screw heads are flushed with the external surfaces of the joined structural members. These joints are subjected to various loadings such as tension, compression, bending, etc. This paper presents the finite element modelling and analysis of a typical screwed Read More …

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 …

Abstract Elastomeric O-ring seals play a crical role in sealing fluids in variety of applicaons across the industries. In spite of their importance, the design of O-ring seals, like any other elastomeric seals is based on heurisc techniques that are formulated by means of exisng experimental and field data. Aempts towards simulang the performance of Read More …

Abstract Informaon required about the primary human moon to design so exoskeletons with a humanmachine interface for the upper limb, is the measurement of accurate muscle force with and without load. The elbow flexion moon of the upper limb is considered here for determining muscle forces. During elbow flexion, muscles aached across the elbow and Read More …
