Solution of Transient Analysis

Ex 51: Perform the Transient analysis of cantilever beam subjected to transient load of 100N for a

period of 0.01 seconds as shown below and determine the following results:

1. Deflection of beam

2. Max. Stress of beam

3. Animate the result

4. Plot the graph between Y displacement vs Time

First sectionStep 1: Do Modelling of beam

a. keypoint (0,0) and (1000,0)

b. line from (0,0) to (1000,0)

Step 2: Define Element Type: Beam 3,

1000

Step2: Now following part divided into 3 parts

Part 1:

In first Part load is not apply. only ALL DOF of left end must be zero.

Part 1 is finished.

Part 2:

In Second Part load is apply. Force applied on right end of beam. Force magitude is 100N in

downward direction.

Direction of force =FY

Value Force/moment value = -100
