Week 4-1D Element Creation Challenge
Aim:
The Aim of this Challenge is to Create the Midsurface of the simple Bracket. Mesh the Extracted Midsurface with Quad & Tria Elements with Element size of 5mm and then create the 1-D Elements between the Brackets.
1. Extracting of Mid_surface:
The Mid surface is extracted for the simple geometry using Auto-mid option. After extraction of Midsurface, the Solid Representation is deleted. The Extracted Mid surface of the Brackets are shown below. The Two Components are Created for Two brackets as shown below.
2. Properties for Brackets:
Inorder to create the Properties for Brackets, two Property Cards are created each with "PSHELL" properties.
The Thickness of the Shell elements are assigned as 2mm for Bracket-1 & Bracket-2.
3. Materials for Brackets:
The Material Card (MAT1) is Created with Properties of steel for Both Bracket-1 & Bracket-2.
4. Washer Splits for Brackets:
The washer Slipts for Brackets were made as shown below,
5. Meshing the Brackets with unit of 5mm.
Brackets are meshed with Quad & Tria Elements with Target length of 5mm.
At Point A:
After Meshing, the RBE2 ELements with Degree of Freedom constrained only for Translational Degree of freedom are Created at the Point A for both Brackets.
The CROD Element is created between the Two Independant Nodes of RBE2 Cluster and the Cross Section properties of Rod are specified.
Cross Section of Rod: BOX
Dimension a= 12 mm
Dimension b=10 mm
Thickness t= 0.75 mm
HyperBeam View:
At Point-B
The I-Beam Section of Given dimensions is created as shown below,
HyperBeam View:
The RBE-3 Cluster is created in the Bracket-1 & 2 with following DOF.
The Beam with I-Cross section is created between the Dependant Node of RBE3 Elements.
At Point C
The x-Rod Section of Given dimensions is created as shown below,
HyperBeam View:
RBE-3 Cluster is created between the Bracket-1 & Bracket-2 with following DOF
The Rod with x-Cross section is created between the Dependant Node of RBE3 Elements.
At Point d&e:
The RBE2 Elements are created at the Points d & e and the rigid mass magnitude of 10 Units is placed over the Independent node of RBE-2.
At Point f:
The Spring Elements are created at the position-f with stiffness of 10N/mm.
Conclusion:
The Midsurface of the Bracket is extracted, Meshed and 1-D element is created between the two brackets.
