Contraction Crack Networks in Basalt Flows

Abstract

The traditional concept of contraction crack formation is based on a model having a regular arrangement of stress centres. A more realistic result is produced if the model consists of a close random packing of stress circles; this gives a crack configuration very close to that observed in real basalt flows.
