What is the difference between "Design by Rule" and "Design by Analysis" in Sec.VIII Div.2?
When we have to apply either of them?

Design by Analysis (Part 5) provides rules on using numerical analysis (typically finite element analysis) to design a pressure vessel to Section VIII, Division 2. There are rules to explicitly demonstrate Protection Against five failure modes: Plastic Collapse, Local Failure, Collapse From Buckling, Cyclic Service: Ratcheting, and Cyclic Service: Fatigue.
Design By Analysis requires specialized knowledge and experience that takes years of practice to build, working with sophisticated computational/numerical models. Design By Rule can generally be performed using much simpler computer programs, but nevertheless requires knowledge and expertise.
