DESIGN CRITERIA for THERMO-PLASTIC MATRIX COMPOSITES (TPMC) and ADDITIVE MANUFACTURING (AM) for POWERTRAIN COMPONENTS

keywords ADDITIVE MANUFACTURING, DESIGN CRITERIA, POWERTRAIN COMPONENTS

Research Groups 20-Progettazione meccanica di motopropulsori e componenti motore

Description The research activity, to be developed not in only one solution but also in several master thesis in parallel or in series each others, is devoted to define new design methodologies, also related to Additive Manufacturing techniques, for lightweight TPMC powertrain components (e.g. connecting rod, piston pin, engine block, engine supports, gearbox casing, etc).
The research is focused also on the identification of specific acceptability limits and failure criteria, as they can be different from those usually known and used.
Specific ad-hoc experimental tests of identification and numerical simulation models can be required and designed for estimating the mechanical behavior, life and reliability assessment of the components. As a matter of fact, mechanical characteristics of TPMC materials depend both on the material and on the manufacturing process, and they are not uniform in the material bulk.
In addition, the identification of parameters involved in the resistance characteristics of the material (static, high and low cycle fatigue, thermo-mechanical fatigue) must be investigated.

Required skills conoscenze meccaniche di base, in particolare in ambito di meccanica del continuo, resistenza dei materiali, progettazione meccanica delle macchine, analisi agli elementi finiti.
