Modify Nonlinear Beam

Nonlinear Beam

Enter the Database name of a nonlinear beam.

Tips on Entering Object Names in Text Boxes.

Properties

Select either Auto Calculate or User Entered.

If you set Properties to User Entered, your template-based product enables the following options. For Auto Calculate, these quantities will be calculated based on the cross-section:

Shear Area Ratio Y/Z

Enter the shear area ratios. Commonly encountered values for the shear area ratio are:

See also "Roark's Formulas for Stress and Strain," Young, Warren C., Sixth Edition, page 201. New York:McGraw Hill, 1989

Ixx/Jxx

Enter the torsional constant. The torsional constant is sometimes referred to as the torsional shape factor or torsional stiffness coefficient. It is expressed as unit length to the fourth power. For a solid circular section, Ixx is identical to the polar moment of inertia . For thin-walled sections, open sections, and non-circular sections, you should consult a handbook.

Iyy/Izz

Enter the area moments of inertia about the neutral axes of the beam cross sectional areas (y-y and z-z). These are sometimes referred to as the second moment of area about a given axis. They are expressed as unit length to the fourth power. For a solid circular section, . For thin-walled sections, open sections, and non-circular sections, you should consult a handbook.

Iyz

Enter product of inertia (available for FE_Part)

Area

Enter the uniform area of the beam cross-section geometry. The centroidal axis must be orthogonal to this cross section.

Damping Ratio

Enabled only when you are modifying a flexible nonlinear beam. Enter the damping ratio applied to the beam elements for the flexible nonlinear beam.

Damping Ratio (Mass)

Enabled only when you are modifying an FE Part beam. Enter the mass damping ratio applied to the FE Part.

Material Type

Select a material type for the nonlinear beam. Your template-based product determines the mass properties according to the density of the material you selected.

Beam Formulation

For flexible nonlinear beams, specify the theory to be used to define the force this element will apply. By default the LINEAR theory is used. If the NONLINEAR option is used, the full nonlinear Euler-Bernoulli theory is used. If the STRING option is used, a simplified nonlinear theory is used. The simplified nonlinear theory may speed up your simulations with little performance penalties.

Sprung Mass %

Enter percentage contribution of part total mass into sprung mass. Select a location of sprung mass contribution from the list for the subsystem with role other than front or rear. (Used only for SVC event)

If you select Table profile, Adams Car displays the following option:

Insert

Will insert the specified numbers of row(s) into location table before the current selection.

Delete

Will delete the specified numbers of row(s) of location table from the current selection.

If you select Outline profile, Adams Car displays the following option:

Outline

Specify the database name of the outline.

If you select B-Spline profile, Adams Car displays the following option:

B-Spline

Specify the database name of the b-spline.

Symmetric

Enabled when you modify component pairs (or brothers):

When you modify a single component, this option is disabled because a single component is by nature asymmetric.

Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:
