Abstract: Foundry sand testing apparatus, method and system are provided for testing foundry sand. A computer foundry sand testing system includes at least one sensor for sensing predetermined characteristics of the foundry sand and for generating a signal. A processor coupled to the sensor processes the generated signal. A display is operatively controlled by the processor for displaying predetermined test information responsive to the generated signal. Predefined displays for receiving user selections and for displaying of test information are automatically generated. The generated displays of test information include real-time stress-strain curves and multiple calculated values utilizing the stress-strain curves.
