Project Type: Failure Analysis
Engineering Discipline: Mechanical

RMA is working with Sibelco on a failure analysis problem in the understanding of premature component failure in a clay processing machine at their Newton Abbot site. The analysis work undertaken by RMA has revealed a likely reason for the fatigue failure and design modifications to the component have been made and will soon be implemented. The validation of these modifications will take some time to appear since the fatigue failure is one that takes many months to develop.

Case Study: Seismic Assessment of a Structure to EC3

Nirvana Engineering designs and manufactures steel structures used in the reserve power industry. Such structures often need to be seismically qualified to ensure that they remain functional in the event of an earthquake. RMA recently conducted such an assessment of two steel structures for Nirvana Engineering. These were analysed using both the Equivalent Static and the Response Spectrum methods in the ANSYS finite element system (ANSYS) and assessed according to the Limit State Design code EC3. RMA have developed a range of ANSYS Parametric Design Language (APDL) scripts to simplify the task of model generation, support application and joint connectivity modelling and to allow easy model verification and sensitivity studies to be conducted. Scripts were also developed for post-processing the results. These make use of raw nodal forces and moments, which are in equilibrium with the applied loads (see NBC07), and provide enveloped data that greatly simplifies the code assessment.

Project Type: Design Analysis Service (On-Site)
Engineering Discipline: Structural

RMA supplied a Security Cleared engineer to provide on-site consultancy at SCX for the structural analysis of a static crane for the AWE Mensa project. The project, which involved static and seismic loading, was the first finite element analysis work undertaken at SCX and detailed verification work was therefore undertaken and a full technical report provided to the client.

"We at Nirvana Engineering required independent verification of an essential supplies seismic battery rack destined for an EDF nuclear site. The project required FE modelling of the proposed rack structure, supported battery system and the projected earthquake loadings. We engaged Ramsay Maunder Associates to undertake this work and found their diligence second to none. They excelled at every level throughout the project and I would not hesitate to recommend their services to any prospective client."

Russell Shaw, Managing Director, Nirvana Engineering (Stafford) Ltd.

"Angus Ramsay, Technical Director of RMA, visited the University of Surrey in late 2016 and presented a seminar titled ‘Research & Development at Ramsay Maunder Associates’ to my final year students on the Civil Engineering courses. The seminar presented a range of advanced topics, including limit analysis, verification and equilibrium methods. Whilst these were difficult topics for my students to deal it was presented in a friendly and easy manner and with skilled use of student questioning in order to maintain interest."
