Week 4-1D Element Creation Challenge
AIM:
Mesh the Given component with the Size of 5 Units. Create 1D elements on the following component with given cross-section and DOF
a. Rod element:- Translational DOF should be Constrained with RBE2 link
Cross-Section: BOX- Dimension a= 12 mm
dimension b=10 mm
Thickness t= 0.75 mm
b. Beam element:- All DOF should be constrained with RBE3 link
Cross-Section: I Section- Dimension a= 8 mm
Dimension b= 10 mm
Dimension c= 8.5 mm
Thickness t1= 0.75 mm
Thickness t2= .6 mm
Thickness t3= .6 mm
c. Bar element:- Constrain only x and y DOFs With RBE3 link
Cross-section: X section- Dimension DIM1= 5 mm
Thickness DIM2= 1.2 mm
Dimension DIM3= 10 mm
Thickness DIM4= 1.2mm
d. & e. Apply the mass of magnitude 10 with the RBE2 link
f. Join the two components with Spring elements
PROCESS:
* step one we will check topoclean up requirement and then extract midsurface from the component.
*now as we know that we need to do meshing of the mid surface we will create washer surface to the circles present on the mid surface.
*now provide 2D meshing to the component with suitable target size.
* while meshing process we take care that there should not be opposite trias ,trias near circular surface and trias on fillets.
* wherever there is 'a' point is mentioned we have allot RBE2 elements with only a translation degree of freedom.
* wherever there is 'b' point is mentioned we have to provide RBE3 links with all degree of freedom.
* wherever there is 'c' point is mentioned we have to provide RBE3 link with only X and Y degree of freedom.
* have to done it by going to the 1D page and selecting the option of rigid and RBE3 respectively.
* then to create ROD,BAR and BEAM we have to go the hyperbeam option.
* inside the hyper beam window ,we select the cross section area as follows:
a. Rod element:- Translational DOF should be Constrained with RBE2 link
Cross-Section: BOX- Dimension a= 12 mm
dimension b=10 mm
Thickness t= 0.75 mm
b. Beam element:- All DOF should be constrained with RBE3 link
Cross-Section: I Section- Dimension a= 8 mm
Dimension b= 10 mm
Dimension c= 8.5 mm
Thickness t1= 0.75 mm
Thickness t2= .6 mm
Thickness t3= .6 mm
c. Bar element:- Constrain only x and y DOFs With RBE3 link
Cross-section: X section- Dimension DIM1= 5 mm
Thickness DIM2= 1.2 mm
Dimension DIM3= 10 mm
Thickness DIM4= 1.2mm
* now connect both the brackets with a Rod ,Bar ,Beam and spring 1D elements.
* we have connected brackets with Rod,Bar and Beam elements with there respective dimensions.
# FOR JOINING SPRING
* for joining two components we use spring elements and use of RBE2 rigid element.
* first, we create a RBE2 element in the end edge of upper component and as well as bottom and then fix the spring element between them.
CONCLUSION: so, here we understood about how to allot 1D elements in terms of Rod,Bar and Beam. we also understood the use and function of hyperbeam.
