How can I make an empirical model to understand composition-processing-hardness relationships?
I've made several disks using calcium carbonate, water, and admixture with different compositions of each of the chemicals. Then I tested the hardness of the disks and hardness of every disk id different due to different chemical composition. Now my idea is making an empirical model using some of the disks I already examined. The hardness will be my response. Now I want to know how can I make an e...
