The Science Behind Karax: Physics-Informed Polymer Aging Prediction 

At Karax, we combine advanced material science with predictive computing to simulate polymer aging, rubber fatigue, and composite degradation—helping engineers predict long-term performance before failure occurs.

Traditional material qualification can take months and cost millions. Karax replaces guesswork with physics-based prediction, combining advanced material models with decades of degradation data. Our ElastoSure platform enables aerospace, defense, automotive, and energy organizations to simulate years of environmental and mechanical aging in just days.

Our Founder

Prof. Roozbeh Dargazany

Dr. Dargazany provides the core technical vision and structural framework of ElastoSure. His research group's pioneering work on Reduced-PINN stiff-kinetics solvers and homogenized fiber-composite mechanics forms the algorithmic foundation for Karax's simulation tools. As Associate Professor of Civil and Environmental Engineering at Michigan State University, Dr. Dargazany leads the High-Performance Materials Group, whose published research on multi-stressor polymer aging under thermal, radiation, mechanical, and hygrothermal conditions is the scientific backbone of the ElastoSure platform.
