TRANSCRIPT
Quantitative nondestructive evaluation (NDE) of materials using ultrasonic and understanding the damage precursor in composites being the primary activities, iMAPS has four diverging research directions:
The Integrated Material Assessment and Predictive Simulation Laboratory
iMAPS Laboratory is strongly founded on ground breaking discoveries and its unique expertise in the field of Acoustics and Ultrasonics,
while exploiting the physics of smart materials. Despite conducting the fundamental scientific research, iMAPS is equally devoted to
contributing real world applications. Its central focus is nondestructive health assessment of the aerospace, mechanical and biological systems.
Modeling virtual NDE experiments and health monitoring of structures (SHM) at multiple length scales using physics based predictive simulation methods for aerospace applications.
Learning the ‘acoustobiomechanics’ of nature and implementing the physics to the design of novel sensors, smart structures, metamaterials and energy harvesters for aerospace applications (patent pending).
Designing application driven ultrasonic, acoustics and photoacoustic methods, namely Q-ACT (patent pending), QUIC etc. to investigate the mechanical landscape and dynamic architecture of the biological species, microbiome, cancer clusters, human tissues, fungi infected crops, infected food, etc. so that alternative remedial action could be taken.
Integrating the structural components with the biological species through predictive bio-origami while exploiting the high entropy fractal architecture and the complex dynamics, to exploit the novel mechano-chemical actuation and sensing possibilities for aerospace, civil and defense applications.
