(*): Indicates material laws compatible with local unit system

(**): Besides materials that already have thermal characteristics inside material law (Embedded Thermal Option), all material laws could define thermal characteristics with /HEAT/MAT, Thermal expansion which defined with /THERM_STRESS/MAT is available for all material laws with shell element and the following materials with solid elements:

Material laws where the number goes from 1 to 28 and laws number 36, 42, 44, 45, 46, 47, 48, 49, 50, 56, 60, 62, 65, 66, 68, 69, 72, 74, 79, 81, 82, 88, 90, 92, 93, 94, 95, 100, 102, 103, 106, 107, 111, 112, 115, 121, 122, 124, 126.

Comments

  1. For shell elements with /MAT/LAW66 and /MAT/LAW25 (COMPSH) and solid elements with /MAT/LAW42 (OGDEN), /MAT/LAW69, /MAT/LAW82, /MAT/LAW92 and /MAT/LAW103 (HENSEL-SPITTEL), it is possible to use /VISC/PRONY to describe viscosity.
  2. All characters beyond the 8th of a keyword are ignored (for example, it is possible to input HONEYCOM, instead of HONEYCOMB).
  3. The Manual Keyword is the keyword of the law, as referenced in this manual.
  4. The Law Number is the material law number used to reference the material law in the fixed format manual.
  5. The Other Available Keywords column features other keywords, which can be used to define the same material law.
