It is a good article however I would disagree that the traditional approach would start with solving the ODE. We normally start using an Laplace transform and writing the transfer funtion. From this, the poles of the system can be identified and any significant problems identified before spending the time to create a complex model.
I would recommend never skipping the back of the envelope analysis. It is very valuble to use it check that your model is locked in.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Pressure vessels are part of common equipment utilized in plants to store liquids and gases under high pressure. It is certain that pressurized fluids will develop stresses in the vessel, which when exceeds failure limits, will lead to hazardous incidents and fatalities.
