Anand, C. (author), Groves, R.M. (author), Shroff, S. (author), Benedictus, R. (author)In this paper we ultrasonic signals from array transducers are simulated using the Thompson and Gray measurement model. The measurement model consists of a beam model, a system efficiency factor which characterizes the response of the electro-mechanical and electrical components of the system, and a flaw scattering model. To inspect layered...conference paper 2020

Çelik, O. (author), Shroff, S. (author), Teuwen, Julie J.E. (author), Bergsma, O.K. (author), Benedictus, R. (author)Laser assisted automated tape or fiber placement (LATP/LAFP) with in-situ consolidation is a promising technique for manufacturing large structures, eliminating the limitations of autoclave curing. Currently, 2-D models are mostly preferred for the thermal analysis of the process. A 3-D, transient thermal finite element model is developed to...conference paper 2018

Anand, C. (author), Shroff, S. (author), Groves, R.M. (author), Benedictus, R. (author)Ultrasonic arrays are used for non-destructive evaluation of structures for aerospace and other applications. With the increase in the usage of fibre-reinforced composites in aerospace structures, this evaluation becomes complex due to the effects of attenuation and reflection from the layer boundaries in composite laminates. Hence there is...conference paper 2017
