I bought an external hard drive with a 3-year warranty in Egypt. The local distributor isn't honoring the standard replacement policy, offering a partial refund instead, which wasn't communicated at purchase. This experience has shaken my trust in WD products. Please help resolve this issue. #CustomerService

AI-everything is the next Dot-com bubble. Folks from the 90's should know. Skepticism and critical analysis is the key to protecting your organization from scammy products with tall claims. If you do that, only real products will stand out.
Check out my commentary video on simulation of potato chips
The potato chip was modeled using about 10,000 shell elements with a brittle cracking material model supported in Abaqus/Explicit. This model assumes that material damage starts when the maximum principal stress reaches a critical value. The compressive behavior is linear elastic without damage. The material parameters are fictitious, as I wasn't able to measure them directly from the experiment.
Regarding the boundary conditions, the lower rigid part was fixed in all directions, and the upper tool moved down at a constant speed until it reached 50% of the initial distance. Lastly, the general contact algorithm was used with a Coulomb friction coefficient of 0.1, which is also an assumed value.
I also performed a simple physical test to compare the results from the Abaqus simulation. You can see that the post-failure behavior in the simulation is comparable to the test. Initially, the damage starts in the middle and evolves until the potato chip breaks in half. After that, the two broken pieces move apart as kinetic energy is converted from the elastic energy stored until the onset of fracture.
With this model, I also tried to investigate the effect of non-uniform thickness on the fracture pattern. I assumed that the shell thickness follows a normal distribution and performed random sampling to assign the thickness to each element.
In the picture, the fracture pattern from the simulation is not as random as the one from the test, but you can see it certainly affects the crack path. We might be able to get a more random fracture pattern if we consider uncertainties like loading direction or loading rate.
