Energy changes in elastic plates due to holes and cracks; pp. 26–33

(Full article in PDF format) doi: 10.3176/proc.2008.1.03


Authors

Reinhold Kienzler

Abstract

The formation of cavities in stressed elastic plates causes changes in their energy. In particular, the change in energy due to the presence of a crack has been extensively studied over the past decades. The paper adds some comments on the old Griffith controversy and calculates then energy changes due to circular and elliptical flaws and, as a limiting case, due to a crack.

Keywords

applied mechanics, Griffith controversy, energy changes, circular hole, elliptical hole, crack, integral.
