Abstract
Taniq develops technology for manufacturers of cord-reinforced rubber products t o improve their product performance and production process through product redesign and supply of software and production equipment. Taniq's technology is used for products ranging from straight large-bore hoses (0600 [mm]) to small bellowed expansion joints (0 < 100 [mm]). The current structural analysis used at Taniq is only able to predict fibre stresses of single-layered products in basic load cases. As many products require local reinforcements and/or multiple fibre layers this basic structural analysis is not proficient. Therefore these products are currently designed by trial-and-error. It is of importance to gain insights in the complete stress state throughout the product in any load case to facilitate a more efficient design process. This stress state can be used for static and dynamic strength predictions, and f o r the development of design guidelines for future products.
