Computer Aided Systems Into Establishing Formulation Of Finite Element Method Of A 2 Dimensional Kirchhoff Plate

For a thin circular plate, stress and strain usually occur in a two-dimensional state. As it is difficult to measure stress, strains are instead measured in real-life practices and its corresponding stress values are calculated. The most popular measuring tool for strain is the strain gauge. Since strain is the measure of change in displacement over the original dimension of a structure, the measuring tool must be sensitive enough to detect that small change in displacement. Thus, we can learn how to handle sensitive measuring equipment and ways to ensure that the data collected is as accurate as possible and also to omit any errors that will affect the final calculation. Besides that, we can broaden our knowledge on multi-channel strain measurements because in reality two-dimensional strains are not

Each separate truss (of the dimensions 920x5x50mm) consisted of a Pratt truss with nine diagonal members on each side of the centre. The model was tested in sufficiently isolated condition by tutors. It successfully passed the initial weight test, and satisfactorily resisted horizontal forces. Once fitted onto the testing rig, loads were applied and increased incrementally. Slight deformation was observed before failing at 12.5 kg, at which force a collection of members failed in succession, concluding the test.

This report aims to describe the experiment performed to investigate the stiffness of a channel section, and in particular calculate the flexural rigidity (EI) of the beam by two different sets of calculations based on the results gained in the experiment. The EI of an object is used

His theory maintains that the truss is a structure that represents beam behaviour. Generally, Culmann considers every connection of the members in a truss flexible (basically a hinge) and formulates equilibrium equations at the point where members meet (Culmann 1851). Nowadays, this theory is known as the "Method of Joints" and is regularly used to calculate the internal forces in each member of the truss. Armed with a method to calculate the forces in the members of a truss, engineers optimized the design of trusses through addition and variation of

The study of large deflection of cantilever beam comes from theory of elasticity. Theory of elasticity state that “solid material will deform under the application of an external force it will again regain their original position when external force is removed is referred to as elasticity”. We took beam made of nickel titanium alloy which regain their original shape after removing external force act on the beam. It’s a prismatic circular cross section beam. Initial shape and curvature of nickel titanium alloy depend upon its length and self-weight of the beam large deflection of combined loading was proposed by kyongoo lee [1] finding deflection of non-linear elastic cantilever beam and solved governing equation using numerical integration of one- parameter shooting method. Bishop and drucker [2] investigate large deflection of cantilever beam of linear elastic material.

Following tables and graphs show the result of the experiment. The tables will demonstrate the experimental and theoretical deflection for each case. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.

The aim of the project is to find the steady-state temperature distribution in a beam. Since it’s impossible to solve the model analytically due to the irregular geometry of the cross-section, the temperature distribution will be found using ANSYS-Mechanical to model the problem and solve using the finite element method.
