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

Object:-

• create midsurface and 2D mesh given componant
• assine property
• create hypermesh element like bar,beam and cross.

Step1:- Import the model in hypermesh and create mid surface

Geo>midsurface

Steap2:-after that create mesh(2D>automesh)

Step3:-Assine the property.

Step4:-Now create connection like RBE2 and RBE3.

Step5:-create rod,beam and cross.

Rod	Beam	cross

conclusion:-

• In this challenge i learn how to create a mesh,mid surface, connection and cross section element.
