![]() The crease patterns are sorted alphabetically based on name. ![]() I tried to link to an actual HTML page on the site wherever possible, but in some cases, this was not possible.Ĭlick on a category title below to expand that category and see a list of all the crease patterns. The link here will take you to the pattern on someone else’s site. Please note that none of these crease patterns are hosted on this site. The difficulty is purely based on how complicated I think the crease pattern looks. The difficulty ranges from Beginner > Easy > Intermediate > Advanced > Super Complex. Crease Patterns marked with a heart are some of my favorites. Here, you’ll find links to many free origami crease patterns from all over the Internet. A themed tessellation, with a sea theme, with squids, rays, and sea turtles. I personally still have trouble doing it, even with simple models. Squids, Rays, and Sea Turtles, Reasonable. It’s much harder to fold an origami model from a crease pattern than it is from a diagram. A crease pattern is basically just an origami model that has been unfolded and shows all the creases on the original flat piece of paper. These findings are size independent and can serve as initial guidelines in the development of new architectured materials for toughness.Crease patterns are a quick and easy way to record how to fold an origami model. These models show that periodic architectures can achieve higher toughness when compared with random microstructures, the toughest architectures are also the most anisotropic, and tessellations based on brick and mortar are the toughest. We identified several toughening mechanisms including crack deflection, crack tortuosity, crack pinning, and process zone toughening. We explored crack propagation and fracture toughness in Voronoi-based tessellations (to represent intergranular cracking in polycrystalline materials), tessellations based on regular polygons, and tessellations based on brick-and-mortar. In this study, we used the discrete element method (DEM) to explore the fracture mechanics of several hundreds of 2D tessellations composed of rigid “tiles” bonded by weaker interfaces. While their architecture can serve as inspiration for the design of new synthetic materials, a systematic exploration of architecture-property relationships in architectured materials is still lacking. Interestingly, natural materials such as seashells, bones, or teeth make extensive use of this strategy. The interplay between the architecture of the materials and the interfaces between the blocks can be tailored to control the propagation of cracks while maintaining high stiffness. In dense architectured materials, stiff building blocks of well-defined size and shape are periodically arranged and bonded by weak but deformable interfaces.
