Mathematical models consist of equations that describe the interrelationship of parameters thought to be important in the development of natural structures.

* '''Mechanics models''' use various analytic and numerical techniques (finite element, distinct element, finite difference) to simulate deformation. Input parameters are undeformed shape, mechanical properties of the model materials, displacements, and displacement rate. The models yield information on deformed shape, displacement trajectories, and the orientation and magnitude of stress and strain in the model at various stages of displacement.

* '''Geometry models''' examine the development of structures, mainly in 2-D, by applying various simplified kinematic or displacement rules. These models do not provide direct information on the structural effects of environmental parameters during deformation (e.g., rock strength, overburden pressure, temperature, strain rate).
