Integrated Theory for Predicting the Hygrothermomechanical Response of Advanced Composite Structural Components

Source

An integrated theory is developed for predicting the hygrothermomechanical (HGTM) response of fiber composite components. This integrated theory is based on a combined theoretical and experimental investigation. In addition to predicting the HGTM response of components, the theory is structured to assess the combined hygrothermal effects on the mechanical properties of unidirectional composites loaded along the material axis and off-axis, and those of angle-plied laminates. The theory predicts values in good agreement with measured data at the micromechanics, macromechanics, laminate analysis, and structural analysis levels.
