3.1
finite element modeling
process of building finite element model, including steps such as building and/or processing of geometric model, definition of material property, meshing and boundary condition application
3.2
material property
set of data describing the physical properties of materials used in the structure of mechanical products
3.3
boundary condition
describing the data information of geometric and physical conditions on the solution domain boundary, such as force, temperature, velocity, displacement and other loads for mechanical products under a given working condition
