FEA testing


Finite element analysis (FEA) is a computerised method for predicting how a product reacts to real-world forces, such as, vibration, heat, fluid flow, and other physical effects. Finite element analysis shows whether a product will break, wear out, or work the way it was designed. It is called analysis, however in the product development process, it is used to predict what is going to happen when the product is used.

Element Analysis (EA) works by breaking down a real object into a large number (thousands to hundreds of thousands) of finite elements, such as little cubes. Mathematical equations help predict the behaviour of each element. A computer then adds up all the individual behaviours to predict the behaviour of the actual object.

Finite element analysis helps predict the behaviour of products affected by many physical effects, including:

  • Mechanical stress
  • Mechanical vibration
  • Fatigue
  • Motion
  • Heat transfer
  • Fluid flow
  • Electrostatics
  • Plastic injection moulding

At OZ-Tac Engineering we have a Registered Professional Engineer (RPEQ) on site at our office in Gympie Queensland, giving us capabilities to provide FEA testing as part of our design service.

The FEA method is comprised of three stages: –

  1. Pre-processing. The engineer develops a finite element mesh of the geometry and applies material properties, boundary conditions and loads.
  2. Solution: The program derives equations from the model and solves the displacements, strains and stresses within the design.
  3. Post-processing: At this stage the engineer obtains results which help to check the validity of the solution. A variety of reporting tools can be used to illustrate the behaviour of the analysis model. The results are interpreted and areas of concerns are discussed, with updates to the design as required.

The Benefits and Application of FEA

FEA is particularly suitable for: –

  • Structural/mechanical engineering design
  • Product development
  • Manufacturing processes
  • Improving the efficiency of existing designs
  • Failure analysis investigations

FEA provides engineering information (Stress/strain, deformation, natural frequencies, etc…) about a component which cannot be obtained by using traditional analysis methods. It is possible to generate a simulation of any design concept and to determine its real-world behaviour under almost any imaginable environments, therefore allowing the concept to be refined prior to the creation of drawings. In turn this creates a lower cost for our customers as less investment is required and changes are inexpensive. Once a model has been developed the analysis helps in evaluating the feasibility of the new design as well as trouble shooting failed designs already in the market and finding solutions without the need to prototype, thus saving time and money.

Non Destructive Testing

Non-Destructive Testing Documentation

Did you know that as a standard part of our company procedure at Oz-Tac Engineering, every project is managed using a compliance document that fully outlines each stage of the individual project, including: –

  • Scope – Overview of the project and the desired outcome
  • Visual examination reports – Including images of the project and the associated standard
  • Welding procedure specifications
  • Test procedure reports and results
  • Design certification
  • Drawing lists

Meaning customised weld procedure documentation can be supplied upon request by Oz-Tac Engineering with every major project. Its something that sets us apart from other engineering companies and its why we maintain a loyal customer base.

As a result, customers are left with a traceable document trail detailing everything that has been actioned by the Oz-Tac team for the duration of the project. Not only does this ensure each project is managed safely and accurately, it also means that in the unlikely event of an issue, it can be tracked to the source and an efficient solution implemented.

At Oz-Tac Engineering you can be assured of service expertise and quality. The Oz-Tac team work to the strict guidelines set under the Industry standard for Australia/New Zealand Structural Steel Welding AS/NZS 1554.5:2004.

If you have a major project coming up and you want an engineering company who takes safety, quality assurance and compliance seriously then contact us at Oz-Tac Engineering for a customised quote.


At Oz-Tac Engineering we firmly believe that the service we offer our customers is paramount to the success of our projects.

Oz-Tac Engineering hold ISO.9001 certification.  This certification is an international standard related to quality management systems.  The ISO.9001 standard provides a framework for business management and is assessed annually by external auditors to ensure the business practices are maintained.  Something which the management and team at Oz-Tac Engineering are extremely proud to have both achieved and maintained.

Oz-Tac became ISO.9001 certified three years ago and management say they haven’t looked back. The certification has increased the effectiveness and efficiency of the company. The systemised approach is fundamental to good business practice (more…)

Company History

Oz-Tac Engineering was founded by Gary Edwards, Luke Edwards and Ty Horne in July 2003.  The idea for Oz-Tac was born after noticing a demand in the industry for onsite project maintenance teams and hence the company was established that same year.   Over the past 14 years the company has grown from the aspiration of three men into an industry leading company employing close to 40 people.  The business is now a well-established engineering and metal fabrication provider servicing the ever-growing timber, mining and quarrying, structural steel, erection and earth moving industries.

There are numerous aspects to Oz-Tac, the first being the project and maintenance teams completing major turnkey projects for timber processing and saw-milling companies. (more…)
