  1. This keyword maps to /MAT/LAW113 (SPR_BEAM).
  2. The material is only used with *SECTION_BEAM, ELFORM = 6 discrete beam elements.
  3. The option “_TITLE” can be added to the end of this keyword. When “_TITLE” is included, an extra 80 characters long line is added after the keyword input line which allows an entity title to be defined.
