Yevgen Gorash is Research Fellow in the Weir Advanced Research Centre (WARC) - research group which works on a range of collaborative projects with Weir Group, a leading manufacturer of equipment for mining, oil and gas and power industries.

His area of expertise and responsibly includes FE-analysis of structural integrity using advanced approaches within non-linear Mechanics of Materials. Objects of analysis and design optimisation are usually products produced by various divisions and companies of the Weir Group located all over the world.

Managerial responsibilities within WARC and department include implementation of research and knowledge exchange projects, coordination with industrial partners, support of early career researchers and supervision of PhD students.

Registrar and tutor for ME105/ME109: Mechanical Engineering Design

The aim of this class is to place the essential elements of design at the heart of courses for Mechanical Engineering students. It shows how the disparate elements of engineering science can be brought together and used to create a safe, durable, and cost-effective solution to a perceived engineering need using 3D solid modelling. The class involves three main activities:

1. Students in groups will create a mechanism using a range of manufacturing techniques and develop an appreciation of hand and machine tools for manufacturing and assembly (buggy class*).
2. An introduction to Engineering Communication, Engineering Drawings, their place within the wider context of the manufacturing process.
3. An Introduction to the Design Process through sketching, 3D solid modelling and assembling using CAD software.
4. Appreciation of modern CAD-CAM techniques and software and development of practical design and manufacturing skills.

Supervising:

• Y4 project students
• Master / EF900 students
• PhD / EngD students

• Ultrasonic Fatigue Testing;
• Residual Life Assessments (based on fatigue and creep);
• Finite Element Analysis (CAE/FEA);
• Continuum Damage Mechanics (CDM);
• Rigid (Multi-)Body Dynamics.

Current research interests comprise study and modelling of non-linear material behaviour: Plasticity and Viscoplasticity, Creep, Fatigue, Hyperelasticity, Unified material models. These non-linear material effects are applied to the residual life assessments of engineering structures subject to severe loading conditions using FEA and concepts of Continuum Damage Mechanics.
