  4. Computes lattice Green's functions in two dimensions for square lattices. The method is a set of recurrence relations implemented in high-precision arithmetic. The square lattice results were needed for a particular research project, which is why this was developed, but similar recursion relations are available for three-dimensional lattices and the same method should work.

  5. This dataset contains code to compute properties of Mode I cracks running in steady state in a triangular lattice. This version of the code was used to prepare graphs for a submission in 2019 to Philosophical Transactions of the Royal Society A in honor of Leonid Slepyan. There are two executable files here. One is 'mode1', which finds locations of atoms in time. The second is 'kelvin_integrate' which finds the relation between loading and crack speed.
