Abstract:
An optical measurement test setup was used to determine the elastic modulus of chemically bonded sand as it is used in foundry applications. The surface of the sand specimen was recorded by a stereo camera system during a 4-pointbending test. The images were used to calculate the material’s deformation. Three different computational methods to determine Young’s modulus were compared. One method was dependent on the displacement data captured by the test machine, and the other two methods...     »
