Cut & curl with point loads

 

01. Idea

The goal of the research was to observe physical behavior of a certain material through a series of sample tests, and understand how the behavior changes by minimal alterations on its physical properties. Based on the founding, the sample units were re-interpreted and converted into digital model using parametric tools and physical engine to simulate and forecast holistic behavior of the entire system composed of the units. of the entire system composed of the units.

The dynamic surface is a combination of 7 by 7 diagonally arranged plastic sheet units. Because of its homogeneous material property, the system doesn’t produce any significant changes in its appearance before individual panels get cut differently.

The cuts and self-weight of the each panel will drive initial deform through the interaction of pulls and pushes between units. The initial deform can be further exaggerated The initial deform can be further exaggerated by supplementary weights at some connecting nodes between panels in a certain area.

02. Material Study

According to our mockup experiments, longer cut tended to generate more curvature changes within a unit, especially when the cut is perpendicular to the direction of pulling forces.Also the amount of load applied to each node of a panel caused significant differences in its surface shape.

03. Digitalizing Process

From the material study, founding is as such; deformation depends on two variables, amount of force/load at each corner and size and direction of open cut. When force is applied at the corners of a sample unit, in addition to the variables, it also comes with constraints to keep its physical properties as same as possible before it finally fails. For instance, lengths of each edge tend to stay same,and its surface wants to relax to flat. Finding equilibrium by combining these two conditions, variables and constraints, was the main challenge of the digitalizing process. By building a parametric model that does exactly what we found described above.

 

04. Pattern Tests

Then by supplying those variables and constraints to physical simulation engine, we tried numerous tests to find the most dramatic combination of loads and cutting patterns. The below are series of test combinations of load / cutting patterns to pick the most dramatic one. The blue represents cutting patterns and the red load patterns.
