Dassault Systèmes’ Post

Who knew? SolidWorks Simulation can crunch numbers for more than just complex machinery designs! Even potato chips can be put to the test with this powerful analysis tool. Can you guess which popular snack brand uses SolidWorks Simulation to perfect their crispy, crunchy creations? #SolidWorks #Simulation #PotatoChips

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. #SIMULIA #DassaultSystemes #Abaqus #Potato

In 2024 this one thing will separate the winners from the losers: Those who were slaves to our tech and those who enslaved our tech. It’s only getting more powerful - use it or be killed by it.

Trivia Time! Here's a brain-teaser for all you tech enthusiasts out there: What was the name of the first computer virus ever created? Drop your guesses in the comments below and let's see who can crack this IT mystery! #TechTrivia #ChallengeAccepted #TestYourKnowledge

Always worth a look, but Ilkka Paananen's blog post today on the state of the company makes for particularly interesting reading. Much of my recent career, as a journalist and a communications leader, has been spent looking at the unique problems and opportunities of startups and scaleups, and in areas related to the creative technology and the creative product of the games industry. So, seeing one of the biggest and best-regarded mobile game studios in the world embrace a model of providing central support for innovative, startup-minded game makers, and then scaling the successes to make impactful live services, is heady stuff. It will be exciting to see what comes out of this. Also very interesting is the frankness of acknowledging the cultural resistance to making big changes - Supercell is, after all, objectively one of the most successful companies in terms of profit generated per employee of all time, and the fear that changes will damage the culture of the studio and lead to the loss of key team members. Change can be scary, and high revenues and profits - while a good thing in themselves! - can be a blocker to taking steps to maintain growth or address fundamental risks that have not yet manifested.

Always a must read, even if just to get into the mind of an executive trying to manage culture and success.

The first computer bug was literally a bug! In 1947, a moth got stuck in a relay of the Mark II computer, causing a malfunction. That's where the term ‘computer bug' originated. #ComputerHistory #TechTrivia #BugInnovation #VintageTech #MarkII #TechAnecdote #HistoricalComputing #MothBug #techmodern #techmoderninsights
