.... A similar development can be generated for moisture-induced stresses. All of the results of this section apply when the moisture swelling coefficients, {β 1 }, are substituted for the thermal expansion coefficients, {α 1 }. Another approach to the calculation of ply stresses is sometimes used...

In this case, in-plane loads are induced at constrained edges by the expansion of the material due to thermal expansion and/or swelling of the matrix from moisture absorption. An interesting aspect...
