Finite Element Analysis

The finite element method is a powerful numerical tool for analyzing mechanical components and systems. The representation of a component or system mathematically with finite element, generally involves a discretization of the structure into many small pieces, e.g. small brick-like elements (hence the name of the method).

  • Designing of a new component or assembly
  • Determining the failure mode of a failed component
  • Analyzing or evaluating an existing component
  • Remaining life assessment of a component


Finite Element Analysis

What areas can FEA be applied?

-  Structure analysis: a cantilever, a bridge, an oil platform

-  Solid mechanics: a gear, an automotive power train

-  Dynamics: earthquake, vibrations of Sears Tower, bullet impact

-  Thermal analysis: heat radiation of finned surface, thermal stress brake disc

-  Electrical analysis: piezo actuator, electrical signal propagation

-  Biomaterials: human organs and tissues

The solution to the equations that govern the behavior of the structure is approximated on each and every brick. The collective effect of all the bricks is taken into account during a step that synthesizes the solutions for each brick to one solution valid for the entire structure. This global solution represents the solution to the equations that govern the structure's behavior. The finite element method provides an accurate tool to predict and evaluate component response, elastic or non-linear plastic, subjected to thermal and structural loads.

Thermal analysis may include convection, conduction, and radiation heat transfer, as well as various thermal transients and thermal shocks. Structural analysis may include all types of constant or cyclic loads, mechanical or thermal, along with non-linearities, such as opening/closing of contact surfaces, friction, and non-linear material behavior.
