Materials

CivilFEM has a materials library, which can be selected through the material. Materials properties (listed in the Script Manual) can also be changed; these are organized through “containers”.

  • Steel: to create a steel material it is necessary de code and the name.

createSteelMat("EC3"," EC3_Fe360")

To change structural steel properties, for example, name, Poisson ratio or thicknesses proceed as follows:

Material("Fe360").Name = "SteelMat"
Material("SteelMat").Poisson = 0.5
Material("SteelMat").Thicknesses[1] = Double(0.15,"m")

It can be also parameterized as below:

m = Material("Fe360")
m.Name = "Mat.Example"
m.Poisson = 0.5
m.Thicknesses[1] = Double(0.15, "m")

  • Concrete: this material is divided in three different ways: concrete, reinforcement steel and prestressing steel. To create a concrete material is necessary the code and the material. As optional argument, the name of the entity can be placed.

createConcreteMat("EC2"," EC2_C12")
createReinfMat("S400","EC2","EC2_S400")
createPrestMat("ECEN10138","EN10138_Y1570C")

To change concrete properties, for example, Poisson ratio, cracking or damping coefficients proceed as follows:

m = Material("C12/15")
m.Poisson = 0.3
m.CrackingProperties.CrackingYN = True
m.DampingProperties.AutocalculateRayleigh = False
m.DampingProperties.AlphaRayleigh = Double(1,"Sec_Inv")

  • Rock: to create rock material is needed to set Rock Type, Rock Subtype, Rock Class and Name, all possible arguments are listed in Script Manual.

createRockMat(“Sedimentary”,”Siliceous”,”Aggregated”,”Flint”)

To change rock properties, for example, Poisson ratio, cracking or damping coefficients proceed as follows:

m = Material("Flint")
m.ElastMod = Double(25000,"Pa")
m.Poisson = 0.2

  • Soil: CivilFEM provides a list of possible soil materials, all included in the Script Manual.

createSoilMat("Peat low plasticity")

To change soil properties, for example, Poisson ratio, cracking or damping coefficients proceed as follows:

m = Material("Peat low plasticity")
m.ElastMod = Double(200000,"Pa")
m.Poisson = 0.35

  • Generic: if you prefer to create an own material, use the generic material, in this command is needed the Elastic modulus, Poisson ratio, Density and the linear thermal expansion coefficient.

# Name,ElastMod,Poisson,Density,ThExpans
createGenericMat("GenMat", 2500, 0.3, 1200, 0)

To change generic material properties, for example, Shear modulus or damping, proceed as follows:

m = Material("GenMat")
m.ShearModulus = Double(52000,"Pa")
m.DampingProperties.AutocalculateRayleigh = False
m.DampingProperties.AlphaRayleigh = Double(5,"Sec_Inv")
