Material server

A material is not arbitrary text. The stable LV material ID is authoritative; designation and temperature-dependent properties are derived from it.

MCP sequence

  1. Search by material number/name with lv_search_materials.
  2. Accept only an engineering-unambiguous match. For exact historical duplicates use the highest LV ID; otherwise ask.
  3. Check K and K' with lv_get_material_strength using temperature, thickness, diameter and AD2000.
  4. Treat V22 as a material ID. The semantic B1 fill plan normally resolves selection and strengths together.
Reference: LV ID 1232 is 1.4571(P) = X 6 CrNiMoTi 17-12-2. At 120 °C, 8 mm and Da 600 mm the verified values were K = 218 N/mm² and K' = 260 N/mm².
If K or K' cannot be resolved, do not continue with guessed values. Fix material service conditions or request explicit engineering-approved values.
