ABOUT ROHIT RAJU MADKE

Skilled in multiscale modeling of mechanical metamaterials and metacomposites using ANSYS®, COMSOL®Multiphysics, and ABAQUS™. Computational mechanics professional with a Doctor of Philosophy (Ph.D.) in Civil Engineering (Structural) from Indian Institute of Technology, Roorkee, India.My Ph.D. thesis proposed two configurations of braided metacomposite, one with 3D auxetic metamaterial and the second with dual-negative (auxetic and negative stiffness) metamaterial. The first configuration helps withstand impact with low and intermediate velocities up to 200 m/s like a bird strike or foreign object strike. The second metacomposite system helps mitigate the body armor plate\'s simultaneous ballistic impact (800 m/s) and shock loads. The multiscale model, progressive damage, and failure of a textile composite at various scales under static loads were simulated using ABAQUS™ with Python scripting and Fortran user subroutines. The dynamic behavior of the metacomposite was predicted using ANSYS® Mechanical, ACP, Autodyn, and LS-Dyna. In addition to Lagrangian mesh, voxel meshing, and meshless SPH techniques were employed at microstructural levels that can aid the designers in simplifying analysis with complex architectures and curvatures. We have utilized additive manufacturing techniques like 3D printing using PLA, nylon, resin, and metal laser cutting.I worked as a senior researcher at the Department of Civil Engineering, Indian Institute of Technology Roorkee, India. My focus was on designing a heat-resistant meta-sandwich structure for an ISRO (Indian Space Research Organisation) funded project utilizing graphite auxetic metamaterials and carbon-carbon semi-auxetic textile composite. Simulations on fracture crack initiation and propagation, including fatigue introspections, were executed with the multiscale finite element (FE) analysis and XFEM using ABAQUS™ and phase-field method using COMSOL®Multiphysics.
