Does anyone know how to apply a load p=-10*sin(x)*sin(y) to a Plate (Shell) in Static Structural Workbench Ansys? if not could you please provide me with the APDL command that i can insert in command section in Static Structural Workbench.

i would very grateful. Thank you

Hello,

To apply a load of the form p = -10*sin(x)*sin(y) to a plate (shell) in Static Structural Workbench ANSYS, you can follow these general steps:

Geometry Setup: Create or import the geometry of the plate (shell) into ANSYS Workbench. Ensure that the geometry is properly defined and suitable for the analysis.

Material Assignment: Assign the appropriate material properties to the plate. This includes defining the material type, such as isotropic or orthotropic, and specifying relevant material properties like Young's modulus, Poisson's ratio, and thickness.

Meshing: Generate a mesh for the plate geometry. Use a meshing method suitable for shell elements, such as quad or tri elements. Ensure that the mesh is refined enough to capture the details of the geometry and the expected behavior of the load.

Boundary Conditions: Define the necessary boundary conditions for your analysis. This typically involves fixing certain degrees of freedom (DOFs) to restrict rigid body motion. For a plate, you might choose to fix the edges or certain nodes to prevent translation and rotation in specific directions.

Load Application: To apply the load p = -10*sin(x)*sin(y), you will need to use the ANSYS APDL (ANSYS Parametric Design Language) commands. Here's an example of how you can apply this load using APDL commands:

a. Launch the ANSYS Mechanical APDL environment within the Workbench interface.
b. Use the *DIM command to define a new parameter, for example, PLOAD, with a value of -10.
c. Use the *DLOAD command to define a distributed load on the plate surface. Specify the load type as "FX" for forces in the x-direction and provide the equation EQUATION to define the load magnitude as PLOADsin(x)*sin(y).
d. Select the faces or nodes of the plate where you want to apply the load using the *CFUN command.
e. Use the *DSLOAD command to apply the distributed load to the selected faces or nodes.

Solution and Analysis: Set up the analysis settings, such as solver options and convergence criteria, and solve the problem. ANSYS will perform the calculations and provide the results.
