Abstract: This disclosure relates generally to enabling a user to (1) determine the radial stiffness of the outer surface of a winding or wound roll, and (2) when coupled with a winding/contact model results in a virtual instrument allowing the user to explore the residual stresses due to winding in roll-to-roll manufacturing process machines, and (3) allows the user to predict winding defects and hence roll quality based upon the known residual stresses. Wound roll models require the input of a radial modulus of elasticity which is state dependent on interlayer pressure. The hardware of the disclosure can be used to determine this radial modulus and serves to enable the user to (1) use winding/contact models and (2) with measurements made during or after winding enable the user to estimate the winding residual stresses.
