Mechanical Engineering Analysis and Test

Focus on Fatigue

MoreVision has developed a number of programs to post-process finite element results, calculate fatigue damage and to plot damage directly onto the FE mesh. The assessments cover code of practices used in many countries (UK - BS7608, France -UIC 515-4 Goodman Diagram, German DIN 15 018, Swedish Volvo standards)

Plastic Analysis
What happens when stress rises above yield? - it may not be as severe a situation as you think.

 ANSYSŪ - Finite Element Software

MoreVision uses ANSYSŪ finite element software. Over a twenty year period it has proved to be both dependable and flexible and has managed to solve every problem we have thrown at it. MoreVision continue to enhance their capabilities by developing libraries of calculation software and ANSYSŪ macros, all of which are available to new clients.

 Fatigue Design Software

One of the most common problems we are asked to consider is the fatigue assessment of welded structures. Unfortunately depending on which industry or which country our client comes from we have to follow different analysis methods (UK - BS7608, France -UIC 515-4 Goodman Diagram, German DIN 15 018, Swedish Volvo standards). Luckily it is often a simple exercise to modify existing software to accommodate new analysis methods. All the software post-processes finite element results and produces damage plots which can be viewed on the FE mesh directly. Weld classifications can also be viewed directly on the finite element mesh which makes the review process much simpler. In addition detailed information regarding any node can be exported to a spreadsheet for detailed interrogation. Almost every page of this web site will feature a project which has benefited from our fatigue processing software.

 Fracture Mechanics Software

Fracture mechanics calculations arise quite frequently, particularly during a failure investigation. MoreVision have a suite of purpose written software for fracture mechanics calculations.

 Parametric Design of Railway Bodyshells

A generic rail vehicle may be sold to a number of different clients. Each client have their own particular preference for seating layout. This means that the positions and sizes of doors and windows change between each order. MoreVision have parameterised this problem so that once window and door sizes have been defined a program which automatically generates a finite element model. In this way any problems regarding resonance, strength of fatigue strength of the bodyshell can be understood during the project definition and tendering stage. The program even produces a bill of materials for tendering purposes.

Top Software Tools

MoreVision have some 20 years experience of problem solving with ANSYSŪ. They have developed a library of macros and software tools customizing ANSYS for specific problems.
Bolted Joint Analysis
MoreVision uses 'Boltcalc' software in conjunction with FEA for fast & accurate assessments.
Partnering Client Design Teams
Will it fall off? Is it strong enough? How long will it last? These are the questions on the minds of many designers. MoreVision can team up to perform simple strength assessments to allow designers to move forward with the confidence that their designs will ultimately satisfy structural criteria.
Independent Design Audits
A fresh pair of eyes can offer an new  insight into design critical problems.
Fixed Price Contracts
Whenever possible MoreVision offers fixed price contracts from the outset of a project.
Failure Investigations
Simply strengthening an area may not give you the results you want and could make the problem worse. Before a solution can even be considered it is imperative that the mechanics of the failure are completely understood.
