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).

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
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 'Calculate minimum RPM to self-balance a CMG on two legs'
Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
