Thinking of taking a PhD Course in that involves Materials Engineering

Hello Theophilus.

I have a different view of your situation- to me the big question is how deep is the Materials Engineering course.

The Aerospace industry Is constantly pushing the envelope of materials science (crack prevention due to fasteners, welding of dissimilar metals and alloys, effects of high temperature plasma on materials).

How you create a digital twin taking into account these specialized processes is not my area of expertise

Hello Mr. Peter,

Thank you for your kind response. I have checked a few documents and courses online. I came across some Stanford University lecture notes. I have been studying through that. I am not sure it is that difficult, looks like you need to understand a lot of atomic, molecular structure chemistry, and physics to understand how they apply to make needed materials for various applications in manufacturing, and construction, while also taking note of how they behave under conditions as you stated in your response. Digital Twin will take all possible conditions in real-life scenarios and simulate all possible outcomes. Data is analyzed and then applied where necessary. That was how I implemented it in my work on Smart factory design. I assume this will be like that too. I may be wrong.

I am still open to discuss this or other topics.

Thank you,

Theophilus.

Hello Theophilus:

Each day I read the official US government newsletter which covers FAA directives on (for example) defects found on Boeing planes  and required corrective actions. A recent example was Boeing using cockpit glass that was not bird resistance. 

Also I watch live youtube videos from Space X that shows the latest fixes to their big rocket made with stainless steel, under development in Texas.

Regarding creation of Digital Twins, what happens when products are many in multiple factories located in different counties with different materials and sub-assemblies. This situation happened when I worked in the IC industry setting up bill of material for all options.

One has to ask what is the lowest level (example down to the fastener level) defined in the Digital Twin? The lower the level the more maintenance work has to be done?
