TWI project leader, Valerio Carollo is set to present at an upcoming IMechE event on ‘Optimising Structural Integrity: Advanced Manufacturing, Materials Development and Analysis Methods.’
The event will take place on 5 November, 2019, at Institution Of Mechanical Engineers (IMechE), 1 Birdcage Walk, Westminster, London SW1H 9JJ.
Valerio is a project leader in the numerical modelling and optimisation group and will present on ‘Additive Manufacturing Process Simulations: From Microstructure to Distortion.’ He is fully involved in the numerical modelling activities in additive manufacturing both for TWI Members and collaborative projects.
His presentation will provide an overview on the common modelling capabilities to predict additively manufactured (AM) parts performances from the micro- to the macro-scale, and will also propose a hierarchical model for the prediction of mechanical properties of AM parts. The presentation will provide an insight on the development, calibration and validation of thermal and mechanical models for the prediction of residual stresses and distortions. Moreover, it will be shown how thermal field predictions are coupled with phase diagrams, JMAK models and G-R diagrams to predict the morphology of the grain structure and, consequently, the mechanical parameters.
Optimising Structural Integrity Event
The Optimising Structural Integrity seminar will address the challenges around the industrial adoption of new testing methods and advanced manufacturing techniques, bridging the gap between academic innovation and industry application. Attendees will gain a clear understanding of new testing and modelling methods that will improve the prediction and monitoring of the structural integrity of advanced manufactured components.
The event will include case study insights from engineers who are adopting innovative advanced material and manufacturing technologies and modelling solutions to reduce risk and obtaining more reliable assets. New methods such as additive manufacturing, electron beam welding and powder metallurgy hot isostatic pressing (PM HIP) have the potential to improve component performance and reduce the cost implications of in-service failure. However, the main barriers to the widespread adoption of advanced manufactured parts, such as the lack of understanding regarding reliability and testing methods, must be addressed. It is important for industry to follow the direction of structural research to encourage the appropriate development of such testing methods based upon up-to-date knowledge.
