Vacuum drying and vacuum drying stress different atmospheric drying, the material will not occur in a vacuum drying drying shrinkage. Conversely, many materials will produce volume expansion after drying, often associated with the expansion of the size of the type of material, moisture content, drying speed, drying temperature and degree of vacuum related. Expansion is anisotropic, often present different laws, there is no unified description of the methods and formulas expansion coefficient. Since there are dry deformation, stress will produce dry, drying stress calculation method is not mature, here borrow material mechanics simple instructions.
