Design Properties define the design space of a Zone or Joint. They contain all of the cross-section, geometry, and material setup for Sizing and Analysis and settings related to the optimization process. They can be imported from FEM or spreadsheet. Design Properties are organized in the Property Tree.
From the Ribbon
Design Property creation mechanisms are organized by type and concept on the ‘Design’ tab of the Ribbon. Select the desired concept to create a corresponding Property.
From the Property Tree
-
Right-click on the desired type.
-
Select the desired concept from the list.
Basic Definition
A Design Property is primarily defined by the following 6 inputs…
-
Name of Design Property.
-
Select between Sizing or Analysis.
Note
Both sets of inputs can exist on the same Design Property.
-
Select between Metal and Laminate material systems.
-
(If Sizing) Choose a Sizing Mode.
-
Define necessary dimensions.
-
Select Material option(s).
Additional Options
-
Composites Sizing Options (see Sizing Options section here).
-
Ply Angle % - Enforce min/max limits on ply angle percentages of laminates.
-
Layup Rules – Enforce rules (symmetry, balance, etc.) on generated laminates.
-
Fabrication Rules – Enforce OML, IML, and midplane plies.
-
-
Advanced Settings – Apply advanced sizing considerations (options depend on concept).
-
Use Analysis - Toggle to use analysis input values for individual design variables.
-
Requested Designs – (Detailed Sizing only) Force HyperX to save multiple viable designs.
-
Tooling Constraints – Force sizing to adhere to tooling constraints (options depend on concept).
-
Dimension Overrides – Used to apply Zone-specific bounds that override Design Property values. For more information on Dimension Overrides, look here for Sizing Overrides and here for Analysis Overrides.
Other Notable Features
-
Zones Assigned - List of Zones currently assigned this Design Property.
-
Zones Selected: List of Zones selected.
-
-
Unassign/Assign - Unassign/assigning (respectively) the current Design Property to all Zones selected.
-
Run - Run Analysis/Sizing on all Zones assigned this Design Property.
-
Set Variables - (Detailed Sizing only) Used to auto-populate min/max bounds with inputs attained from Rapid Sizing.
-
# Candidates - (Detailed Sizing only) Calculated total number of Sizing candidates resulting from the dimension and Material inputs supplied.
There are three types of Design Property.
Panel
A Panel Design Property defines the Sizing and Analysis inputs required for a 2-dimensional Zone (made up of shell elements). Once a 2D Zone has been assigned a Panel Design Property, HyperX will see that Zone as a 'Panel' and sort it accordingly in the Structure Tree. This Design Property - including Sizing Mode, dimensional bounds, fabrication considerations, etc. - is explicitly defined on the Panel Design Property Form.
Important
A Panel Design Property must be assigned to a 2D Zone before it can be Analyzed or Sized.
There are several different panel concepts available in HyperX, each with their own respective Design Property inputs.
-
Plates - Unstiffened isotropic concept.
-
Laminates - Composite solid laminate concepts; one, two, or three stack.
An example Laminate Design Property is shown below.
-
Sandwich Panels - All concepts with a top and bottom facesheet (metallic or composite) separated by a core (foam, honeycomb, grid, trusscore, etc.).
An example Sandwich Panel Design Property is shown below:
-
Stiffened Panel - Open Sections - Concepts with a skin and attached stiffener that has open geometry (I, Zee, etc.).
An example Open-Concept Stiffened Panel Design Property is shown below:
-
Stiffened Panel - Closed Sections - Concepts with a skin and attached stiffener that has closed geometry (Hat, etc.).
An example Closed-Concept Stiffened Panel Design Property is shown below:
-
Grids - Concepts with multiple integral stiffeners at various intersecting angles (orthogrid, isogrid, waffle grid, etc.).
An example Grid-Stiffened Panel Design Property is shown below:
-
Frames - For panels with an attached frame.
An example Frame-Stiffened Panel Design Property is shown below:
Beam
A Beam Design Property defines the sizing and analysis inputs required for a 1-dimensional Zone (made up of bar elements). Once a 1D Zone has been assigned a Beam Design Property, HyperX will see that Zone as a 'beam' and sort it accordingly in the Structures Tree.
There are several different beam Design Property concepts available in HyperX, each with their own respective inputs:
-
Open Sections - Concepts that have an open geometry (I, Zee, etc.), shown in the rise-up list below.
An example Design Property for an open section beam concept is shown below.
-
Closed Sections - Concepts that have a closed geometry (tube, box, etc), shown in the rise-up list below.
An example Design Property form for a closed beam concept is shown below.
Joint
Connections between two Zones, whether physically represented in the model or considered along the edge between two Zones, are defined for Sizing and Analysis using a Joint Design Property.
Important
A Joint Design Property must be assigned to a Joint before it can be Analyzed or Sized.
HyperX offers a multitude of different Joint Design Properties:
-
Edge Allowable - Generalized joint concept where only the overall joint allowable load is used.
-
Fastened - Joints with one or more rows of fasteners (single lap or doubler).
An example Fastened Joint Design Property is shown below:
-
Riveted - Joints with one or more rows of rivets.
An example Riveted Joint Design Property is show below:
-
Bonded - Joints with bonded adherends (single lap, scarf, clevis, etc).
An example Bonded Joint Design Property is shown below:
Design Properties are organized by type on the Property Tree. They are assigned to any selection of Zones by:
-
Dragging the Property from the Tree and dropping onto the selected Zones in the Viewport.
-
Dragging the Property from the Tree and dropping onto the desired Structure or Set in the Structures Tree.
-
Right-click on the Property and select ‘Apply to Visible Selection'.
-
Select ‘Assign’ in the Design Property form.
The Property Tree is automatically filtered to only show Design Properties that are included in the currently loaded Project. However, Design Properties can be shared between Projects in a Database using the Design Property Library.
Tip
The Library also includes options to Create/Edit/Delete Properties and Import Properties from another Database.
