• To account for the compression mechanism of damp powders, the change of specific volume was measured and the relation between stress and strain was analyzed. From these results, the compression of damp powders was divided into three stages as the following resistance regions : (1) the region under the control of agglomeration energy between adjacent particles, (2) the transient region, depending on the interlocking of particles, and (3) the region of resistance by mutual friction of movable particles. In the case of (1), the relation of the compressive work to the agglomeration energy of damp powder was demonstrated, and was semi-theoretically expressed by an equation of compression states.Furthermore, a correlating equation between compressive stress and void fraction in the transient region (2) was derived by applying Athy''s equation for the data of compression (3).
