Week 4-1D Element Creation Challenge

Objective:

Create 1D elements on the given components (parallel brackets) with given various cross and DOF

Procedure:

1) Import the Geometry model given in IGES file format

2) Extract Midsurface from the given Geometry and save as Midsurface component(Geo>Misurface)

3) Create Material and property with Pshell CORD Element and assign to Midsurface component

4)Create washer splits over the midsurface model and save.(Geo>quick edit>watersplits lines)

5)DO automeshing with mesh size=5units over the Midsurface component an d save the model(2D>Automesh>select surface>mesh)

6) Create the Rigid links RBE2 and RBE3 Between the holes as follows(1D>Rigids>create)

RBE2-à a-a,d-d,e-e

RBE3--àb-b,c-c

7)Create Cross section –Crod,Cbar,Cbeam as per given dimensions(1D>Hyper Beam>std section)

8)Create properties and assign to above cross sections

9)Create 1D rod ,1D bar and 1D Beam elements and assign property(1D>Bar/rod/beam)

10)Now Rod element created between the holes a-a ,Bar element created between the holes b-b and beam element created between the holes c-c .

11)create masses between the holes d-d and holes e-e(1D>masses>create)

12)Create Spring 1d elements between Edges d-d and Edges e-e(1D>SPRINGS>create)

13)Now Final parallel bracket is created

Files attached:

1)Final parallel bracket model in .hm file format

2)Meshed parallel bracket model .hm file format

3)property file in .png format

4)rod element cross section-Box in .bmp file format

5) bar element cross section-I section in .bmp file format

6)Beam element cross section-Cross in .bmp file format
