Summary of Research achievements and highlights

The focus of research is the development of mathematical models based on the principles of advanced mechanics for analysis of composite/sandwich plates and shells integrated with piezoelectric layers. My research achievements and accomplishments are given below.

• Three-dimensional static and dynamic models are developed for piezolaminated angle-ply panel and plates subjected to arbitrary boundary conditions. The significant extensions made to extended Kantorovich method to make suitable for analyzing three dimensional problems. It is demonstrated through a series of numerical studies that the present methodology can accurately predict the edge effect or boundary effects at very clamped or free edges.


• Recently, this technique has been extended to develop an accurate 3D elasticity solution for rectangular FGM plates with longitudinally varying material properties.


• This development has opened the area for developing the close form solution for FGM plates with property variation along multiple directions


• Very recently, first time, an analytical model is developed for static analysis of arbitrarily supported composite cylindrical based on 3D elasticity. Here also, it is observed that present technique converge very fact and predict edge effect accurately.


• Further, this technique can be employed or extended to provide analytical solution for many classical and new engineering problems.


• The prediction of response of hybrid laminated structures integrated with PFRC layers requires an accurate determination of their effective properties. To address the above concern, a fully coupled, 3D micromechanical model was presented first time for computing the effective electro-thermo- elastic properties of a unidirectional PFRC lamina with the poling and electric field applied normal to the fiber direction.


• The most accurate global as well as local layerwise response of hybrid laminated structures can be obtained by the exact analytical solution of the equations of three dimensional (3D) piezoelasticity. In this direction, benchmark analytical 3D piezoelasticity solutions for the static and dynamic response of simply-supported hybrid cylindrical shells of revolution and shell panels integrated with monolithic piezoelectric or PFRC layers are presented.


• Two-dimensional static and analytical solution of Levy-type rectangular hybrid plates is also developed based on a recently developed coupled efficient layerwise zig-zag theory.


• Two-dimensional static solution for all round arbitrary supported plates are also developed using the EKM method. These solutions can act as benchmarks to assess numerical solutions.


• Dynamic analysis of piezoelectric based energy harvester is developed which may help to develop prototype models for energy harvesting purpose.


• Recently received the Young Engineer Award from INAE -2017, SERB Women Excellence Award 2019 and DUO-India Professor Fellowship-2020


• The above developments will help in designing and developmental phase of components in aerospace, civil, consumer products and medical science field which in turn help to make better products under Make in India scheme.
