The material library includes many material models that represent most civil engineering construction materials. Many models exhibit nonlinear properties such as plasticity. All properties may depend on time.
Material properties considered by CivilFEM include standard properties (Young Modulus, Poisson ratio, etc.) as well as other properties necessary for specific calculations, such as properties related to codes: characteristic strength, yield strength, reduction coefficient, etc.
Additionally, there are several dependent parameters in a material’s data which are automatically updated. Therefore, the user must account for these values when modifying those related properties.
CivilFEM materials have five different kinds of properties:
General properties: common properties for all kinds of materials.
Material properties: reserved for steel, concrete, etc.
Code properties: related to Eurocode 2, Eurocode 3, ACI, CEB-FIP, etc.
Active properties: obtained for the actual active time.
General properties are common to all categories of CivilFEM materials and contain data identifying the materials (name, reference, type…); mechanical properties and the activation times of each material.
Specific material properties are always available for a particular material, regardless of the code under which the material was defined.
When defining a material inside CivilFEM, standard properties are automatically assigned but the user can modify these properties at any given time. Additionally, there are several dependent parameters in a CivilFEM material that are automatically updated. Therefore, the user should check these values when modifying the related properties.
The following types of materials can be defined in the current version:
