Fellow of the Indian National Academy of Engineering (INAE)
His main research concerns Finite element method, Wave propagation, Mathematical analysis, Lamb waves and Graphene. The Finite element method study combines topics in areas such as Beam, Frequency domain and Classification of discontinuities. D. Roy Mahapatra combines subjects such as Zigzag, Numerical analysis, Condensed matter physics and Wavenumber with his study of Wave propagation.
His Mathematical analysis research is multidisciplinary, incorporating elements of Damage detection and Anisotropy. His research investigates the connection with Lamb waves and areas like Signal which intersect with concerns in Piezoelectricity and Ultrasonic sensor. His work is dedicated to discovering how Mixed finite element method, Fourier transform are connected with Composite material and Delamination and other disciplines.
His primary areas of investigation include Composite material, Finite element method, Nanotechnology, Structural engineering and Piezoelectricity. His Composite material research incorporates themes from Nanowire and Molecular dynamics. His study in Finite element method is interdisciplinary in nature, drawing from both Discretization, Frequency domain, Mathematical analysis, Wave propagation and Delamination.
D. Roy Mahapatra works mostly in the field of Wave propagation, limiting it down to concerns involving Acoustics and, occasionally, Coupling. His research integrates issues of Field electron emission and Condensed matter physics in his study of Nanotechnology. His Piezoelectricity research is multidisciplinary, relying on both Ultrasonic sensor, Wafer, Lamb waves and Structural health monitoring.
D. Roy Mahapatra mainly focuses on Composite material, Optoelectronics, Graphene, Molecular dynamics and Nanotechnology. His Composite material study frequently links to other fields, such as Finite element method. His Finite element method research is multidisciplinary, incorporating perspectives in Time domain, Acoustics, Bulk modulus, Matrix and Delamination.
His work carried out in the field of Optoelectronics brings together such families of science as Piezoelectricity, Thin film and Nanostructure. He interconnects Porosity, Silicon, Continuum, Graphite and Condensed matter physics in the investigation of issues within Graphene. His biological study spans a wide range of topics, including Biomedical engineering, Plasmon and Drug.
His scientific interests lie mostly in Composite material, Graphene, Composite number, Lamb waves and Guided wave testing. Much of his study explores Composite material relationship to Finite element method. The study incorporates disciplines such as Deformation mechanism, Viscoelasticity, Gallium and Strain hardening exponent in addition to Finite element method.
His Graphene research includes themes of Lattice, Silicon and Molecular dynamics. His studies deal with areas such as Ultrasonic sensor and Wafer as well as Lamb waves. He usually deals with Guided wave testing and limits it to topics linked to Wave packet and Computer simulation, Wave propagation, Time domain and Reflection.
