Shock waves in crystals - temperature effect

AI Thread Summary
Inducing shock waves in covalent crystals using ultrashort laser pulses raises questions about estimating temperature rise related to pressure, particularly at tens of GPa. While some participants express skepticism about the original poster's knowledge, others emphasize the importance of understanding shock wave dynamics and diagnostics. Accurate temperature calculations are possible with the right equipment and a grasp of shock speed. A suggestion is made to consult proper textbooks rather than relying on Wikipedia for foundational knowledge. The discussion highlights the need for a solid understanding of shock physics before conducting experiments.

If you induce a shock wave in a covalent crystal using an ultrashort laser pulse, is there any way to estimate the temperature rise in relation to the pressure? Say I want to induce pressures of 10's of GPa. Is there a general way to think of this problem? I know next to nothing about shock waves.
Thanks.

If you know next to nothing about shock waves, what business do you have in shocking a material with an ultrashort laser pulse?

If you're not going to provide any information, what business do you have posting in the thread?

But hey, if you really need an outlet to be condescending, go right ahead.

Anyway, I'll have you know that I wasn't intending to start inducing shocks in my lab's photodetector until I'd at LEAST read the wikipedia article.

Look, I work in the field of shock physics diagnostics, so I have at least a gross concept of what you're trying to do. Quit getting defensive over a valid question.

What is it you're trying to accomplish in these experiments? It is possible to calculate the temperature given the proper diagnostics, but do you have a concept of how fast the shock is going to be and what kind of equipment you're going to use to measure the shock?

So, you're going to design a shock physics experiment based on a (non existent) shock physics article on Wikipedia? You'd better get a proper textbook on the subject first.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
