Abstract
The theory of elasticity of materials is presented, and related to the elas ticity displayed by fat crystal networks. A review of the theory and method s used to determine the yield point, or hardness of a fat crystal network u sing cone penetrometry is provided. Experimental relationships of elastic m odulus to cone penetrometry measurements are provided and discussed. It was found that the shear elastic moduli of fat crystal networks are directly p roportional to the hardness of the network as measured by cone penetrometry , for some eight different fat systems.
