Reversible Process

Grains of sand. In limit of infinitesmal changes, system moves through equilibrium states during transition-->reversible process. Reversible Process. Remove one grain of sand at a time. Allow system to equilibrate. Pressure decreases by very small amount.

Hygrothermal behavior of composite laminates

Hygrothermal behavior of composite laminates. Composite materials can absorb moisture and expand in the same way that they expand due to temperature. We can use the same kind of analysis to deal with stresses that arise from both. In this course we will focus on thermal behavior.
