Abstract
The prediction of the stress distribution in the powder bed is important for the design of the storage vessel and the unit operation of the powder. We calculated the stress distributions in a plane stress field by using the constitutive equation of powder based on the plastic potential and Coulomb-Mohr criteria, and the incremental finite element method.
We also measured the wall stress distributions and compared them with the calculated results. They agree with each other in the horizontal stress distribution of the side wall as well as in the vertical stress of the bottom. Hence, the constitutive equation and our simulation method are reasonable and would be useful for the design of the powder storage vessel.
