@@junaidhussain4781 Not sure I understand that question properly but based on the fact you said a bunch of tests have been performed, you can look at the resulting damage of the material. So the microstructure of a ductile deformation is different to that of a brittle deformation. From this, you can know whether it’s a ceramic or a metal (majority of the time, obviously the ductile to brittle transition in metals needs to be considered as well) and from this you can analyse other material deformations and use your pattern recognition to work out what material it is?
