Week 4- Challenge

Objective

To create 1D elements with given cross-section and DOF.

Procedure

• First import the model that has given to you.
• Then generate mid surface of that model using mid surface option from geometry tool.
• Create properties and materials in model view.
• Assign the material that has been provided to you and also you can specify the name of material. Like here I have mentioned as steel.
• Like this in properties section also we have to mention as these are shell elements and materials as steel.
• As we have holes in our model need to do washer split for better meshing in curvature area.

Path: Geometry – Quick edit ­­­– Washer Split.

• Then go for meshing. Select the automesh option – select the surfaces for meshing – define element size – select the mesh type – then click on mesh.
• Then create rbe2 and rbe3 element, assign dofs on meshed model as per your requirement.
• Create 1D element by clicking elements from both brackets.
• Here I have provided CROD for box section, CBEAM for I-Section, CBAR for cross-section, and CELAS1 for spring.
• For defining of cross-section of each element go to hyper beam option. Create 3 different cross-section for box, I-Section and cross-section. Define dimension for each section as per given to you.
• For defining masses on the bracket click on the element and assign the magnitude you want to.
• In properties also we have to create for box, I-section and cross-section then only we can define 1d element as per given specification.
