There are various versions of the Gilbert tessellation, which are easily generated by changing some parameters in the algorithm, defining the crack shape (horizontal and vertical line, angled line, arc, curve etc.).
In the following files you can download some of the generated patterns: Simple Gilbert's tessellation patterns, Gilbert's tessellation with axis Parallel Cracks, Gilbert's Tessellation with a Constant Direction and Multiple Cracks...
Plus a bonus: Fracture patterns
