Chapter 3: Using the Function Tool The Function Tool allows you to define a dependent variable as a function of one or more independent variables. Using the Function Tool, you can define complicated boundary conditions on a model, or you can define the nonlinear material behavior for a joint element. Example 1 Suppose that the applied displacement at a node of the model is a function of temperature and velocity. The function is defined as follows: u = (-0.007 * T + 0.50) V r where T is the temperature and V r is the relative velocity. The Function Tool allows you to input the function, thereby specifying the boundary condition at that node. Example 2 Suppose the nonlinear damping force characteristics in a joint element varies quadratically with temperature and linearly with velocity. The function is defined as follows: F = f(T) V r or F = (C 1T 2 + C 2T + C 3) V r where C 1, C 2, and C 3 are constants, T is the temperature, and V r is the relative velocity. The Function Tool allows you to input the function along with the constant values, thereby incorporating the damping characteristics by specifying a nonlinear force that varies with relative velocity and temperature. The following Function Tool topics are available: 3.1. Function Tool Terminology 3.2. Using the Function Editor 3.3. Using the Function Loader 3.4. Applying Boundary Conditions Using the Function Tool 3.5. Function Tool Example 3.6. Graphing or Listing a Function For more information, see Specifying a Function Describing Nonlinear Stiffness Behavior in the Element Reference. 3.1. Function Tool Terminology The Function Tool has two components: • Function Editor -- Creates functions. • Function Loader -- Retrieves the functions and loads them as table arrays. The following terms apply when using the Function Tool: Release 13.0 - © SAS IP, Inc.
