As illustrated in the provided image, this ParamML code defines a specific geometric shape resembling an "I-beam" calculates its mechanical properties using section functions following a consistent pattern of combining the word "section" with a property identifier.This pattern is likely designed to make the functions self-explanatory and easy to understand. |
