The results obtained by Fortran program were validated with Reddy [27][17], clearly showing the influence of environment, explained by the hygrothermal deformation growth. While increasing the environmental values the shape of stress is generally preserved in all loading models. Weak influence is observed on the shear stresses with models MTCF1-5, where behavior is the same due to the dominance of hygroscopic constraint imposed by fick law.
