Is there an electrical analogue to mechanical fatigue with respect to dielectric strength?
It depends.
When the limit (15 kV/mm) is given for the material, it should indicate severe transport mechanisms, like:
electrons accelerated
creating free ions on their path
accelerating said ions
...

What does cycle mean in fatigue strength diagram?
A cycle in terms of fatigue strength is going from no load to full load back to no load.
The frequency that the load is applied and removed is measured and there have been some well-documented ...

Will a thin overcoat of silicone sealant protect a non-waterproof adhesive underneath?
No. If silicone conformal coatings are anything to go by, they are not rated for submersion. One of the reasons you don't want air pockets on a silicone conformal coating is that water will collect ...

Will a thin overcoat of silicone sealant protect a non-waterproof adhesive underneath?
The basic question is: can you buy any kind of paint at all that will keep moisture from diffusing into the glue line? Now you can see that you need to know how long you want the glue joint to last ...

How do I calculate the strength to weight ratio of a material
You need to know what kind of loading and geometry you have. You also need to know if you are volume limited or mass limited. You can't just have a part of identical geometry and compare. You need to ...

How do I calculate the strength to weight ratio of a material
The best strength to weight ratio depends on the type of loading. I.e. if the loading is in tension of flexure the strength to weight ratio changes.
A unified way to access materials is the concept of ...

Converting data from Chaboche material model from ABAQUS to ANSYS
Rate independent means it does not depend on time. Example of rate dependent would be creep, where constant stress leads to constant strain rate in time ($\dot{\epsilon} = \frac{d\epsilon}{dt} = const$...

What is the longest lasting modern building material?
Steel buildings are a more long-lasting and modern building material compared to wood or any other material because durable steel better resists general causes of deterioration such as termites, ...

Calulating the compression deformation using strain data measured by strain gauge _ material engineering
First a disclaimer: that you can't really precisely obtain the actual deformation of the specimen, you can only get an estimate. The result will be dependent on the geometry of the specimen (if its ...

Units of measurement for structural analysis
DISCAIMER: I haven't used calculix.
From this page, I found out that there are 3 predominant unit systems that are being used
m,kg,s,K : meter, kilogram, second, Kelvin
mm,N,s,K: millimeter, N, ...
