PERFORMANCE BASED DESIGN AND MATERIAL SELECTION RESEARCH

An integrated approach has been adopted in majority of our research to combine fundamental and engineering lab characterization with physics based mechnistic modelling and principles of life cycle assessment.

Performance Based Integrated Research Approach
