Week 4-1D Element Creation Challenge

Aim: To generate mid-surface from a 2D element and to create 1D elements to it.

Pre-requisites:

• Geometry
• Hyper Mesh software

Overview:

• Import geometry to Hyper Mesh software
• Generate mid-surface
• Create RBE2, RBE3 and spring connections where ever required
• Create 1D elements to RBE2 and RBE3 connections.

Procedure:

-Firstly, import the geometry to Hyper Mesh software.

-See if the geometry is good or not

-Now, generate mid-surface for the given geometry by using mid-surface option from geom.

-Differentiate the mid-surface by giving different properties to each mid-surface.

-Generate washer splits at the holes.

-Generate mesh for mid-surfaces.

-Now, create RBE2, RBE3 and spring connections where ever it is mentioned in the question.

-Now, to create 1D elements. We need to go to 1D and select Hyper Beam in that you need to select what 1D elements you want to create.

-Once, you select which element you want to create hyper Mesh will take you it’s Hyper Beam interface where you can edit the dimensions of the elements.

-Now, you can revert back to the Model view by selecting the model view option which is present on top left corner.

-Create properties for 1D elements that you have created.

-Now, create the elements with the help of bars and rods deck.

-Assign each 1D elements property to each element.

Objective:

From this week challenge, I have leant how to give connections, how to create a 1D element and how to assign those created 1D elements to the respective RBE2 and RBE3 connections.

Conclusion:

For the given 2D element mid-surface has been generated and 1D elements have been created.
