Task 1: Finite Element Analysis

FEA consists of a computer model of the material or design, and emphasizes, analyzes the results. It is used in the new product design and refinement of existing product range. The company is able to verify that the proposed project can meet the specifications of the customer before the manufacture or construction (Reddy, 2003). Changing an existing product or structure is used to qualify a product or structure for the new conditions of service. In case of failure, FEA may be used to determine changes in the design to be adapted to new conditions.

FEA uses a complex system of points called nodes to make the grid called a mesh. This network is programmed so that the material and structural properties as mentioned define the structure responds to certain stresses (Hughes, 2000). Node in a certain density of the material, depending on the expected level of stress a certain area (www.solidworksguru.com). Regions that receive a lot of stress tend to have higher density nodes as those who experience little or no stress. Landmarks can be made of: turning point of the previously tested material, fillets, corners, intricate detail and high tension. Grid is like a spider web that from each node, extending element mesh for each of the neighboring nodes (www.sv.vt.edu). This web-based vector carrying the material properties to an object, creating a set of elements (Reddy, 2003).

Task 2: FEM-simulation and analysis software solver Runtime

Two key features have been sustained has been used for finite element method. First, FE-modeling of amount of CPU time, and second, they are showing high I / O Continuous improvement in the size and complexity of the finite element models, the actual available resources of the ...
