IMPACT

Welcome to IMPACT Laboratory in the Department of Mechanical and Aerospace Engineering (MAE) at the Indian Institute of Technology Hyderabad (IITH)! Here we develop engineering solutions through an integrated multiscale framework to transform the design methodology for high-performance structures and materials.

We aim to address the scientific and engineering challenges in developing multifunctional materials through novel, advanced experimental and computational frameworks. Our lab focuses on the fundamental understanding of physical processes at various length (nm-mm) and time (ns-ms) scales, governing the dynamics of materials that give rise to their multi-functional behavior at the structural scale.

You will find a brief introduction to our members, Alumni, research, and publications on this website.

OUR LATEST RESEARCH

International Journal of Plasticity

A crystal plasticity finite element (CPFE) model was developed to investigate strain partitioning in HEA. Model parameters were calibrated against experimental tensile data using a representative microstructure, enabling accurate prediction of phase-specific deformation behavior.

Mechanism and Machine Theory

Developed a topology optimization framework for soft pneumatic grippers with design-dependent pressure loading, using a Darcy-based pressure model. The optimized, SLA-printed grippers demonstrated superior grasping performance compared to conventional designs and were experimentally validated on a variety of objects.

A combined Finite Element - Material Point (FEMaP) simulation of wave propagation under a Hypervelocity impact in a particle reinforced composite.

The video shows the delamination (Experimental (top) and Simulation (bottom)) of Ammonium Perchlorate particle embedded in the Hydroxyl-Terminated Poly-butadiene matrix under a tensile load. The HTPB/AP composite is an energetic material used as a solid propellant.

Non-ordinary State-based Peridynamic (NoSP) simulation of damage evolution under high-velocity tensile loading in an HTPB-AP composite.

A Mechanical Raman Spectroscopy (MRS) set-up to obtain stress maps in the material under load. The sample shown is a single Ammonium Perchlorate particles embedded in the Hydroxyl-Terminated Poly-butadiene matrix. The HTPB/AP composite is an energetic material used as a solid propellant. The composition of the above-shown composite is 80% AP and 20% HTPB. MRS measurements are used to measure in-situ stress and temperature for thermo-mechanical characterization of the particle-binder interface.
