Pset_MechanicalBeamInPlane Properties about Mechanical Beam in Plane. IfcMaterial IfcMaterial YoungModulus A measure of the Young's modulus of elasticity of the material. Young Modulus YoungModulusMin Elastic modulus, minimal value, α=0°. YoungModulusPerp Elastic modulus, mean value, α=90°. YoungModulusPerpMin Elastic modulus, minimal value, α=90°. ShearModulus A measure of the shear modulus of elasticity of the material. Shear Modulus ShearModulusMin Shear modulus, minimal value. BendingStrength Bending strength. TensileStrength Indicates the ability to withstand breakage apart under applied force. TensileStrengthPerp Tensile strength, α=90°. CompStrength Compressive strength, α=0°. CompStrengthPerp Compressive strength, α=90°. RaisedCompStrengthPerp Alternative value for compressive strength, α=90°, which may be used under material and code dependent conditions (e.g. if deformation is tolerable, or far from ends of the member); conditions should be stated in SELF\IfcProperty.Description. ShearStrength Shear strength. TorsionalStrength Shear strength in torsion. ReferenceDepth Depth in bending for which the mechanical properties are valid; provided as a means to check the integrity of material assignment. InstabilityFactors Defining values: slenderness ratios; defined values: either factors or divisors of the strength, depending on the design method (if <1: factors, if >1: divisors).
