Structural mechanics, elasticity and strength of materials

The design of structures requires always the dynamic analysis. Civil structures, this analysis is essential to prevent the serious effect of earthquakes and wind actions. Structures of transport dynamic analysis is essential since they always have rotary systems that xindex some sort of vibration. Aircraft and space vehicles are subjected to modal analysis to ensure their integrity. In this course, you will enable the student to use the General techniques for the analysis of vibration and the dynamic behavior of structures. Learn how to analyze and control vibrations experienced by lightweight structures. Analyze the vibrations and dynamic actions produced by the effect of wind and earthquakes on structures. This course will allow students to analyze the dynamic response of simple structures such as structures of bars of chassis of cars, robotic arms etc.

Lectures, classes to resolve doubts in small groups, student presentations, tutorials and personal work, oriented to the acquisition of knowledge (1.5 ECTS). - Lab and classes of problems in small groups, individual tutorials and personal work, oriented to the acquisition of practical skills related to the program of the course (1.5 ECTS). Due to the uncertainty about the teaching format to which the health circumstances will lead us during the next course, it is expected to start in the semi-attendance mode, and may lead to training 100% classroom or 100% online depending on the evolution of the spread or control of the pandemic and the health and hygiene standards dictated by the authorities of the sector.
