Calculate high temperature pipeline ExA (EA), expansion force modulus (EAα), EI (ExI), second area moment (I), Z modulus and Poisson ratio for multi layer pipelines.
Only include the Young's modulus value for the layers which will contribute to the stiffness. The second area moment (I) and Z modulus are calculated for the line pipe. The stiffness of the other layers is included, and is factored by the relative stiffness of the layer. The Z modulus is calculated at the mid wall of the line pipe. External coatings are ignored.
