Analysis by Firth, Finite Element Analysis, FEA, Stress Analysis, Engineering Software  


We are an Engineering Technical Consultancy company, based in Wigan, Lancs, with over 30 years experience in Finite Element Analysis (FEA) and Stress Analysis.Employing a skilled team of engineers with a wide range of experience including road and rail vehicles, aerospace and industrial plant.

Our Principal, Nigel Firth has been the owner & Technical Director of Analysis by Firth since 1993. Clients include household names from sectors including Commercial & Public Service Vehicles (Buses), Aerospace, Train manufacturers, buildings & general manufacturing.

We are experts in static and dynamic finite element analysis, stress and fatigue analysis with extensive experience in investigating service problems and carrying out accident investigations. Specific examples include:

Calculations on various aspects of a new design of universal access toilet for railway carriage refurbishment.
Calculations were supplied to the Vehicle Acceptance Body and were accepted in full by them. Finite element analysis of two different sizes of plastic bottles to ensure they could be stacked on multiple pallets. Natural frequency and forced response analyses of a large multi-storey building to ensure that foot fall would not be a problem. Finite element analysis of a composite blended wing body UAV, which was a concept study for future passenger aircraft. This was subsequently successfully flight tested.

The above represents a small proportion of finite element and stress analysis we have carried out over many years. For more details of other work and how Analysis by Firth can assist see OUR SERVICES page.  

"A team of highly qualified engineers providing cost effective solutions to your analysis requirements with fast and effective turn around on all types of analysis"

Our sister company Software by Firth is a reseller for FEMAP with NXNastran and can provide training in the use of FEMAP with NXNastran.

Training Courses

Analysis by Firth offers training in all aspects of engineering design and stress analysis together with Introductory and Advanced courses for FEMAP with NXNastran. Rather than being presented by lecturers with purely an academic background, all our courses are presented by Engineers with many years of experience in industry. It is our aim to provide a sound practical basis for the technique rather than just a theoretical discussion of the method.


We can help you to develop your design through the prototyping stage, without the need for costly prototype manufacture and testing.
