Question

For 1-D bar elements if the structure is having 3 nodes then the stiffness matrix formed is having an order of ​

Answer 1

Answer:

ONE DIMENSIONAL ELEMENT

Bar and beam elements are considered as One Dimensional elements. These elements

are often used to model trusses and frame structures. Bar is a member which resists only

axial loads. A beam can resist axial, lateral and twisting loads. A truss is an assemblage of

bars with pin joints and a frame is an assemblage of beam elements.

have a great day

Answer 2

Concept Introduction: 1D elements are really brittle in Chemistry.

Explanation:

We have been Given: For 1-D bar elements if the structure is having 3 nodes then the stiffness matrix formed is having an order of 

We have to Find: For 1-D bar elements if the structure is having 3 nodes then the stiffness matrix formed is having an order of ?

For 1-D bar elements if the structure is having 3 nodes then the stiffness matrix formed is having an order of 

$3 \times 3$

Final Answer: For 1-D bar elements if the structure is having 3 nodes then the stiffness matrix formed is having an order of 

$3 \times 3$
