Week 4- Challenge
Creat 1D elements on the following component with given cross-section and DOF
a. Rod element:- with only translational DOF and RBE2 link
Cross-Section: BOX- Dimension a= 12 mm
dimension b=10 mm
Thickness t= 0.75 mm
b. Beam element:- with all DOF and 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:- with only x and y DOFs With RBE3 link
Cross-section: CROSS 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 RBE2 link
f. Join the two components with Spring elements
Procedure:
1)Midsurface Extraction:For the given component extract the midsurface from the given slid which is sheet of 5mm thickness.
for extraction of midsurface auto midsurface and select select the surface,click extract so thatit will create midsurface.We can change the type selection by extraction option shown in the figure1.1 and fig1.2 show the midsurface of the component.
2)Meshing:Here 2D meshing is done by automesh(2D)
3)Creating RBE2 and RBE3 And joining:
RBE2:is the 1D element with infinite stiffness also called Rigid element.
create RBE2 by (1D>rigids).For the location we can select as a noe or multiple nodes with degree of freedom
RBE3:RBE3's are interpolation constraint elements,where the motion of a dependent node is defined as the weighted average of the motion of a group of independent nodes.THe dependent degree of freedom and weighting factors can be specified or automatically calculated based on the geometry.
Join all respective nodes of RBE2 and RBE3 as per memstion cross section with locations
for bar and beams we can use bar (1D>rod) inside we have define type of element from CBAR,CBEAM.
forrod we can rod (1D>rod),inside we have definite of element from CROD
for Create mass from masses tool(1D>massess)select the node and assign mass to it.
4)Create hyperbeam:in hypermesh we can create different standard cross section such as I,L,T etc
for creating 1D>hyperbeam>standard section>>select the hyperbeam>select the type of section and click create
it will open new window to input the valve.input the given shown in the below
cross-section and DOF:
a.Rod element-with only translation DOF and RBE2 ink
Cross section:BOX Dimension a=12mm
dimension a=10mm
thickness t=.75mm
b.Beam element:- with all DOF and RBE3 link
Cross-section:I section -dimension a=8mm
Dimension b=10mm
Dimensionc=8.5mm
thickness t1=.75mm
thickness t2=6mm
thickness t3=6mm
c.bar element:-with only x and y DOFs with RBE3 link
Cross-section-dimension DIM1=mm
thickness DIM2=1.2mm
Dimension DIM3+10mm
Thickness DIM4+1.2m
Result:Deploy the mesh and create 1d element on the given component with given cross section and DOF is done
