Force Balance Equations/<br />
Herring Equations<br />
• The Herring equations[(1951). Surface tension as a motivation<br />
for sintering. The Physics of Powder Metallurgy. New York,<br />
McGraw-Hill Book Co.: 143-179] are force balance equations at<br />
a TJ. They rely on a local equilibrium in terms of free energy.<br />
• A virtual displacement, δr, of the TJ (L in the figure) results in no<br />
change in free energy.<br />
