In this article the studies on moisture diffusion process, hygroscopic stresses and moisture-induced vapor pressure are reviewed, with the emphasis on the theoretical analysis, parameter characterization and its experimental measurement and validation, as well as the finite element simulation.

According to the model of axial symmetry in semi unlimited body, the absorbing moisture stress of adhesion coating under water pressure is studied, which is caused by the difference of absorbing moisture property between filling particulate and adhesion coating basis.

Calculating of thermal or humidity stress and architectonics for reinforced concrete rectangular pond;

In this paper,the author presents forword a new theory in rock mechanics-the humidity stress field the- ory of swelling rock.

Using Arrhenius model and Eyring model,the reliability properties of LCD electrode corrosion were studied by corrosion acceleration experiments of LCD electrode with thermal stress & humidity stress,and a typical verifiable LCD life was derived.

Effects of moisture diffusion and hygrothermal stress on reliability of SCSP;

Analysis of thermal stress and hygrothermal stress for SiP device in reflow soldering

Then, thermal stress and hygrothermal stress of lead-free solder joint are simulated and calculated separately, and their performances are analyzed and compared.
