The attached pdf is written in tensor calculus and it is a bit confusing. I want someone to explain to me 2 equations specifically these are equations 148 and 150.
The first step to explain them is to write them in a simple format. A format that is not confusing using simple matrices.
Second step involves explaining this six canonical elastostatic and constant 4th order tensor using simple.
Third use an example (that I have) to explain to clear any misunderstaning
Please read the project description. I have preference to university professors and actual PhD holders.
