Modeling air blast on thin-shell structures with Zapotec

Bessette, Gregory B.; Bessette, Gregory B.; Vaughan, Courtenay T.; Bell, Raymond L.; Attaway, Stephen W.

A new capability for modeling thin-shell structures within the coupled Euler-Lagrange code, Zapotec, is under development. The new algorithm creates an artificial material interface for the Eulerian portion of the problem by expanding a Lagrangian shell element such that it has an effective thickness that spans one or more Eulerian cells. The algorithm implementation is discussed along with several examples involving blast loading on plates.
