Our group presented three papers at the Fourth Biot Conference on Poromechanics, held June 8-10, 2009 at Columbia University, New York (http://www.civil.columbia.edu/biot). Dr. Rosa Espinosa Marzal discussed “Crystallization pressure of crystals confined in pores” in which she showed that the deformation of stone by crystallization of salts can be quantified using poromechanics. Prof. Jean Prévost presented “Finite-Element Analysis of the Bending of a Saturated Beam”, in which he showed that the analytical solution that we use in measurements of permeability agrees very well with a finite element simulation. Other analytical treatments of this problem, using different approximations, are less successful. Prof. George Scherer (seen above) discussed the “Effect of Air Voids on the Dilatation of Mortar During Freezing”, showing that the measured strain in mortars with entrained air can be explained quantitatively by using poromechanics. This paper is based on the thesis research of Zhenhua Sun.
