Analysis Properties are used to assign selected failure methods (organized by Failure Modes) to Zones and Joints for Sizing/Analysis. Analysis Properties are organized in the Property Tree.
A Failure Mode is a collection of related analysis methods, their state, and their respective factors and settings. They are associated with a specific category of criteria - for example, Metallic Strength is a category, and the corresponding Failure Mode will contain Von-Mises, Max Principal, and the various directional strength methods HyperX supports for isotropic plates.
Tip
For more information on available criteria and how they're used, check out the articles in the Theory category.
Failure Modes are stored in the Database Library. They are selected to define Analysis Properties, which are then assigned to Zones/Joints. These are the methods that will be evaluated for each Zone/Joint prescribed during Analysis and Sizing.
The image above shows a Panel Buckling Failure Mode. All failure methods that fall under the Panel Buckling category are available to toggle, and their corresponding Analysis Settings can be defined accordingly.
Note
For each type of Failure Mode, the criteria and settings may vary, but the overall functionality of the form remains the same.
Working with Failure Modes
Create
From the Ribbon
Failure Mode creation mechanisms are organized by type and concept on the ‘Analysis’ tab of the Ribbon. Select the desired concept to create the corresponding type of Failure Mode.
From the Analysis Property Form
Select the ‘Create a new failure mode’ option.
Organize
Failure Modes are organized in the Library found below the Property Tree. From here, they can be selected for inclusion in as many Analysis Properties as needed.
An Analysis Property is a collection of Failure Modes. When assigned to a Zone or Joint, they define the analysis criteria used to write margins of safety for that Zone/Joint. Analysis Properties are stored and managed in the 'Analyses' node of the Property Tree. An example Analysis Property applicable to a sandwich panel design is shown below.
Types
There are three types of Analysis Properties.
Panel
A Panel Analysis Property collects the Failure Mode selection required to define the failure criteria assessed for 2-dimensional Zones (made up of shell elements).
Important
A Panel Analysis Property must be assigned to a 2D Zone before it can be Analyzed or Sized.
An example metal Panel Analysis Property is shown in the image below.
There are several different Panel Analysis Properties that can be automatically created (see Create Analysis Property). These are based on the possible Panel Design Property concepts and the corresponding failure criteria that are typically applied to Zones of that definition. These concepts are listed below rise-up menu.
Additionally, the following Failure Mode categories are applicable to Panel Analysis Properties:
-
Temperature
Beam
A Beam Analysis Property collects the Failure Mode selection required to define the failure criteria assessed for 1-dimensional Zones (made up of bar elements).
Important
A Beam Analysis Property must be assigned to a 1D Zone before it can be Analyzed or Sized.
An example Beam Analysis Property is shown in the image below.
The following Failure Mode categories are applicable to beam analysis properties:
Joints
A Joint Analysis Property collects the Failure Mode selection required to define the failure criteria assessed for Joints.
Important
A Joint Analysis Property must be assigned to a Joint before it can be Analyzed or Sized.
An example Fastened Joint Analysis Property is shown in the image below.
There are several different Joint Analysis Properties that can be automatically created (see Create Analysis Property). These are based on the possible Joint Design Property concepts and the corresponding failure criteria that are typically applied to joints of that definition. These concepts are listed below rise-up menu.
Additionally, the following Failure Mode categories are applicable to Joint Analysis Properties:

Define
Organize and Assign
Analysis Properties are organized by type and concept on the Property Tree. There are a few ways to assign them to any selection of Zones or Joints, such as:
-
Dragging the Property from the Property Tree and directly onto the selected Zones/Joints in the Viewport.
-
Dragging the Property from the Property Tree and directly onto the desired Structure or Set in the Structure Tree.
-
Right-click on the Property and select ‘Apply to Visible Selection'.
