INGEO works on structural analysis that comprises the set of physical laws and mathematics required to study and predict the behavior of structures.
The subjects of structural analysis are engineering artifacts whose integrity is judged largely based upon their ability to withstand loads; they commonly include buildings, bridges, aircraft, and ships.
 Structural analysis incorporates the fields of mechanics and dynamics as well as the many failure theories. From a theoretical perspective the primary goal of structural analysis is the computation of deformations, internal forces, and stresses.
In practice, structural analysis can be viewed more abstractly as a method to drive the engineering design process or prove the soundness of a design without a dependence on directly testing it.
To perform an accurate analysis a structural engineer must determine such information as structural loads, geometry, support conditions, and materials properties. The results of such an analysis typically include support reactions, stresses and displacements.
This information is then compared to criteria that indicate the conditions of failure. Advanced structural analysis may examine dynamic response, stability and non-linear behavior.
There are three approaches to the analysis:
- the mechanics of materials approach (also known as strength of materials);
- the elasticity theory approach (which is actually a special case of the more general field of continuum mechanics);
- the finite element approach.
The first two make use of analytical formulations which apply mostly to simple linear elastic models, lead to closed-form solutions, and can often be solved by hand.
The finite element approach is actually a numerical method for solving differential equations generated by theories of mechanics such as elasticity theory and strength of materials.
However, the Finite Element Analysis (FEA) depends heavily on the processing power of computers and is more applicable to structures of arbitrary size and complexity.
