How Can Comsol Model Time and Space Varying Pressure in Laser Shock Peening?

AI Thread Summary
Comsol can effectively model time and space varying pressure in laser shock peening, despite challenges in implementation. Users have noted that while many studies utilize Abaqus for simulations, Comsol offers a more realistic approach by allowing direct modeling of laser-material interactions. This capability includes handling heat transfer effects and potentially mechanical effects with some modifications. Additionally, Comsol's flexibility enables users to incorporate their own partial differential equations (PDEs) for unsupported phenomena. Overall, Comsol is a viable alternative for simulating complex pressure variations in this context.

TL;DR Summary
Hello, is it possible to simulate laser shock peening process in comsol?
Hello, I am trying to learn comsol but I couldn't find how to apply the pressure that changes respect to time and space.

I have pressure function from articles that I read but couldn't implemented on comsol,

and in most studies people make the simulation with Abaqus software so I am not sure that I can make same in comsol.

Modeling this in Comsol should be not only possible but also more realistic than in Abaqus. To simulate such process in Abaqus you have to apply time- and spatially-varying pressure while Comsol allows you to model laser-material interaction directly. It’s meant for heat transfer effects but there’s a good chance it will work with mechanical effects as well (maybe after some modifications - Comsol even allows you to add your own PDE’s to model various unsupported physical phenomena).

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'What type of toilet do I have?'
I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
