Method for estimation of internal gas pressure in pores of model spherical specimen
An analytical expression is proposed for determining the internal pressure of gas in a pore, obtained on the basis of solving the problem of elasticity theory on the deformation of a spherical cavity located in the center of a hollow sphere. It can be useful in evaluating the properties and structure of products produced by powder metallurgy methods and additive technologies, as well as for improving these technologies.
