Dr.Mohammed Hamoud
• Be able to predict the state of stress and strains in simple mechatronic • components. • Be able to apply the more adequate failure criteria and answering to • factors such as the type of solicitation applied, the geometry, the • material they are made of or the environment in which they must • work. • Be able to optimize the parameters concerning the design of • mechatronic components such as geometry and materials to improve • its behavior in failure conditions. • Be able to analyze the safety of cracked components and components • with stress concentrators submitted to mechanical and thermal loads. • Be able to design mechatronic system components subject to simple • or combined stresses. • Be able to select the most suitable joint configurations between • simple components of a mechatronic system. • Be able to predict the service life of components in real-life service • conditions
