Argyris Visiting Professorship 2020 for Michael Ortiz

Since 2014, the Argyris Visiting Professorship honors internationally renowned scientists from Germany and abroad, who are outstanding representatives of their discipline in the field of simulation science. In 2020, Michael Ortiz, the Frank and Ora Lee Marble Professor of Aeronautics and Mechanical Engineering at the California Institute of Technology, is awarded with the Argyris Visiting Professorship from the Stuttgart Center for Simulation Science at the University of Stuttgart.

"It is with great pleasure that we finally can announce Michael Ortiz as this year’s awardee for the Argyris Visiting Professorship. Being a SimTech Senior Fellow since 2011, Michael has a long-standing and firm connection to SimTech and its members. With his current research focus on data-driven computational mechanics, he acts at the core of SimTech's research paradigm of data-integrated simulation science. We are thus delighted to confer SimTech's 2020 Argyris Visiting Professorship to Michael Ortiz and look forward to various interactions and collaborations in the diverse and inspiring field of data-integrated simulation science“, announces SimTech spokesperson Thomas Ertl this year’s decision.

Michael Ortiz has been one of the world's leading figures in the field of applied and computer-oriented mechanics for decades. In recent years, he has increasingly turned to data-driven methods of computer-oriented mechanics. Here, he developed a formalism that integrates the response behavior of materials into a continuum mechanical model exclusively by means of data points, thus making the formulation, calibration and evaluation of a material model superfluous. The methodology developed by Michael Ortiz has since been known under the term "data-driven computational mechanics” and has caused quite a stir in the scientific community. His original publication from 2017 has led to a large number of papers and numerous citations from various working groups.

"Michael Ortiz is a leading researcher at the forefront of computational solid mechanics. He has made various seminal contributions to the field of mechanics, including variational formulations, discretization methods as well as advanced computational models of inelastic material response across several length and time scales. Recently, he formulated a new paradigm of data-driven computational mechanics, which makes him an even greater inspiration for SimTech.”, Marc-André Keip, Institute of Applied Mechanics (CE) and PR in the Cluster of Excellence SimTech, explains his reasons for nominating Michael Ortiz.

We are extremely glad to welcome Michael Ortiz as SimTech's Argyris Visiting Professor 2020 in Stuttgart and look forward to vivid discussions and fruitful collaborations. Michael Ortiz will be staying in Stuttgart from the beginning of October until the end of December and present his research during a public Argyris lecture. So far, there is neither a set date nor format for that lecture due to the given circumstances of the COVID-19 pandemic. As soon as the date is fixed, we will inform you on our website and our social media channels.
