Specification of isotropic material data of pipe (Input Table)

Data description/conditions:

MATREF:

Reference name of material data

Unique name in list

If a custom or prescribed material has been selected in MATL, then material data of the selected material will be automatically filled in this table.

Various icons will be shown if the material name is not unique, or some of the material data defined are in conflict with the predefined materials.

Emod:

Young's modulus of pipe material

> 0.

(Emod(steel) = 2.07E05 N/MM**2)

Gmod:

Shear modulus of pipe material

> 0. / Undefined

(If Gmod = Undefined the value will be calculated according: Gmod = Emod/(2*(1+Nu)), Gmod(steel) = 0.8E05 N/MM**2)

Nu:

Poisson's ratio of pipe material

≥ 0. and ≤ 0.5

(Nu(steel) = 0.3)

ALPHA:

Coefficient of thermal expansion of pipe material

> 0. and < 5.e-4

(ALPHA(steel) = 1.2E-5)

Re:

Yield stress of pipe material at 20 degc

> 0.

ReT

Yield stress of pipe material at t degc

> 0. and ≤ Re / Undefined

(If Undefined, ReT equals Re.)

WEIGHT:

Weight of material

> 0. / Undefined

(W(steel) = 7.70E-5 N/mm3)

(In case the deadweight is calculated this material weight is used)
