Profile

Provision of specialist consultancy services in structural integrity, fracture mechanics, fatigue, creep, defect assessment, computational analysis and expert witness advice.

Dr. Martin Goldthorpe has 30 years experience in structural mechanics, finite element analysis, fracture mechanics and structural integrity assessment. After graduating from Imperial College, London in 1977 with a First Class Honours degree in physics, he spent three years in the automotive friction materials industry. He returned to academic life to undertake PhD studies in numerical fracture mechanics at the Mechanical Engineering Department, Sheffield University. Following spells of post-doctoral university research, and employment in the power generation and engineering software industries, he formed M. R. Goldthorpe Associates in 1993.

Fracture Mechanics Training

In 1998, Dr. Goldthorpe joined Professors Adrian Demaid, Ian Howard and John Yates in Fracture Training Associates. FTA has presented the renowned Sheffield Fracture Mechanics training course every year since 1980.

Autumn 2009 Course

The Autumn 2009 course will again be held at The Old Hall Hotel, Buxton. The dates are Tuesday 29 September to Thursday 1 October and Tuesday 13 to Thursday 15 October. You can find the brochure here. At present, 16 delegates have reserved places and so there are 14 places available. Please email Adrian to register your interest, make an enquiry, or make a provisional booking.
