How about the actual stress distribution of a bolted connection? Stress
distribution has a similar situation, and idealization is necessary. Most
structural professionals do not have a problem with idealizations. That may
simplify the work. Possibly you are the only one who likes to criticize
Stress distribution on RC section is also complex. Idealization make design
work simple. It is nonsense to criticize idealizations.
