Update: I found a typo in the modeling I presented last week. I has been revised. The new model makes sense by looking at the trends. The model is validated at some extreme situations (e.g. then crease folding angle alpha=180deg). Out-of-plane bending is added to the analysis. So now we ha...

Using the analytical model developed last week, with certain geometry constraints, stiffness of the proposed orthogonally assembled double-layer corrugated structures have been evaluated. Using design parameters optimized from maximum stiffness requirements, a rectangular shape sample and a circular...

This week, I did quite a lot of literature review and a lot of math to convert the complicated model to a simple but really applicable version. The model can convert the corrugated sturcture to simple plates by redefining the equivalent material properties (Young's modulus mostly). Using this model,...

For the past few days, I have been studing the mechanical behaviors of accordion shape folded structures. I have also been studying the science of paper sheet, which is quite complicated. I have developed a mathematical model to predict the in-plane stiffness of both single-layered accordion shape f...

I did some research on different models to predict behaviors of foldable structures. The most useful (simple but sufficient) model for me to use is called "Bar-Hinge Model". It simplified foldable structures into bars and nodes. It can track the in-plane stretching and out-of-plane bending.
