Section B: Finite Element Analysis (total 75 points)
A truss frame depicted in the figure below consists of three elements. All of them have the
same material properties i.e. Young’s modulus E=200 MPa, Poisson’s ratio ‹=0.3, diameter
of circular profile d=10 mm and length L=1 m. The frame is supported by one roller and
one fixed support and is loaded with concentrated force of 2kN at node 3. Using any FEA
software (preferably Abaqus) create a corresponding numerical model and calculate the

Figure 1: Truss frame structure
✏ displacements for all nodes
✏ forces for all nodes
✏ forces in all elements
✏ reaction at supports
✏ stress in all elements.
Verify your FEA results by application of suitable analytical method and hand calculations
of support reactions and forces in elements. Prepare a technical report which includes:
description of the problem, presentation of numerical model, presentation of FEA results,
presentation of hand calculation and comparison between hand calculation results and FEA.
The technical report should not exceed 5 A4 pages and should be written using Arial, 12-
point font size.
The coursework will be marked out of 75. The marking scheme for the assessment is given
