II.1.7 CTE and CME calculations

One assumes a linear dependence of the temperature on the location through the laminate thickness:

T(z) = T0 + zT,z.

Similarly, the water uptake depends linearly on z:

H(z) = H0 + zH,z.

The calculation of laminate response to hygrometric loading is very similar to its response to thermo-elastic loading. Therefore, the following developments are done for thermo-elastic loading only. Later, they are transposed to hygrothermal solicitations.

  II.1.7.1 In-plane and flexural thermo-elastic behavior
  II.1.7.2 Out-of-plane shear thermo-elastic behavior
  II.1.7.3 Hygrometric behavior of laminates
