Abstract

Professor Antonino Morassi is one of the most preeminent scientists in the area of Inverse Problems related to Mechanics of Solids and to the Theory of Structures. He arrives in Sao Paulo in October and will be based at the Department of Mechatronics and Mechanical Systems Engineering of the University of Sao Paulo (USP) for 3 months. During his visit he will execute the research “Dynamic behavior of spider orb-webs and related inverse problems” . The spider orb-web is a complex biological-mechanical system that has attracted increasing interest in the scientific literature in the last four decades. This web is a natural, lightweight, elegant structure with an extreme strength to weight ratio that is rarely observed among other structures, either natural or man-made. Its primary functions are for catching prey and sensory information, and the study of the mechanisms guiding the spider in prey capture and gathering information through web vibration has been - and actually is - one of the main objectives of the research in this field. A series of conferences and three lectures directed to different kinds of audiences are planned for his visit. Professor Morassi will certainly be an inspiration for young researchers, and the field of Inverse Problems in Brazil will be greatly benefited. (AU)
