6.3. Stresses, strains and displacements due to exposure<br />

The temperature distribution at the end <strong>of</strong> exposure and end <strong>of</strong> cooling down<br />

subsequent to the exposure, respectively, was the basis for the evaluation <strong>of</strong> stresses,<br />

strains and displacements as presented below.<br />
