Key Concepts in Finite Element Method (FEM) Analysis
Fundamental Concepts in Finite Element Method (FEM)
Sources of Nonlinearity:
- Constitutive relations (material)
- Changes of geometry (strain, displacements)
- Boundary Conditions (contact)
- Loads (deformation)
Why FEM is Important:
- It replaces a continuous structure with a model having a finite number of points.
- It describes physical phenomena for which analytical solutions are not known.
Nonlinear Elastic Materials:
Present nonlinear stress-strain relationships even at infinitesimal strains.
Linear Elastic Materials:

Operating Cycle
The operating cycle is the average period of time required for a business to make an initial outlay of cash to produce goods, sell the goods, and receive cash from customers in exchange for the goods. This is useful for estimating the amount of working capital that a company will need in order to maintain or grow its business.
A company with an extremely short operating cycle requires less cash to maintain its operations, and so can still grow while selling at relatively small margins.

Quadrilaterals: Shapes & Properties
What is a Quadrilateral?
A quadrilateral is a four-sided polygon.
The interior angles of a quadrilateral add up to 360°.
Types of Quadrilaterals
| Type | Properties |
|---|---|
| Square | All sides equal, all angles 90°, opposite sides parallel |
| Rectangle | Opposite sides equal and parallel, all angles 90° |
| Rhombus | All sides equal, opposite angles equal, diagonals bisect at right angles |
| Parallelogram | Opposite sides equal and parallel, opposite angles equal |
| Trapezium | One pair of opposite sides |

What is human reality?
Human reality encompasses everything that lies beyond the border of the skin, extending into the world we perceive and interact with.
What are the areas of human reality?
The areas of human reality include:
- The world of perception
- The inner somatic world (body sensations)
- The psychic world (thought, emotion)
These are all integrated into a single, unique reality that varies from individual to individual.
What did Immanuel Kant call the ‘thing-in-itself’?
It refers to the ultimate reality,

[30] Choose a number r larger than any |bi|, and say that the scaled benefit bi0 of keeping application i on the old system is bi0=r, while the scaled benefit of moving it is bi1=r+bi. So our problem is equivalent to that of finding a partition of the applications that maximizes the sum of the scaled benefits minus the sum of pij for all pairs i and j that are split. Define a directed graph G=(V,E) with nodes s,t,v1,v2,..,vn, edges (s,vi),(vi,s) of capacity bi0,(t,vi),(vi,t) of capacity bi1, and
