Y direction deflection correction Following last week's blog post, I modified our design tool. The new results show a better match for y-direction deflection. Here are some of the results: 1. FCFC, clamped on longer edges, forces on shorter edges (a) Stress distribution (b) x direction...

1. Here is the intermedium results: plane stress of a CFFF rectangle plate, with uniaxial load The magnitude is the same, results are close (at least visually). Stress u direction displacement v direction displacement (results do not match well, but this is not the direction of interes...

There are three steps I will take in order to implement this design tool: Step 1: Verify I operate correctly in FEA (Solidworks Simulation). In order to do this, I will use some existing numerical solution and/or analytical solutions to find out critical buckling load. Then I will apply this criti...

As mentioned in the last blog post, there are two steps in solving buckling problems The first step is to calculate plane stress in the system. This step converts external load (in-plane load) into stress distribution in the plate, so as to be used later in the second step (buclking analysis) T...

Here is the design toolbox that I am currently implementing: Currently, I am implementing potential energy in plane stress analysis. The direct outcome will be the in-plane displacement and stress distribution. As soon as I get those results, I will compare them by: (1) using simple cases such a...

There are two things I would like to demonstrate: We can rapidly complete iterative design, for a device that failed initially. We can predict failure ahead of time. There are more things I would like to show: - A. Our design tool can be used on different materials Isotropic materi...

Validation of our approach How compare accuracy There are different ways of comparing result accuracy: Ratio of the maximum deflection calculated by the numerical solution to the corresponding values obtained analytically [1] [2] Ratio of deflection of deflection at a particular point...
