Title: Geoffrey Juan Desmeure: Innovator in Structural Modeling and Stress Analysis

Introduction

Geoffrey Juan Desmeure is a notable inventor based in Moissy-Cramayel, France. He has made significant contributions to the field of structural engineering through his innovative patents. With a total of 2 patents, Desmeure has developed methods that enhance the understanding and modeling of structural behavior under various loading conditions.

Latest Patents

One of Desmeure's latest patents is a method for modeling an element of a structure using finite elements. This method simulates the behavior of a structure by finite element calculation, where a global model represents the entire structure, a local model focuses on a specific area with geometric details, and an auxiliary model represents the area without those details. The process involves determining a nodal displacement field in the global model, applying it to the local and auxiliary models, and calculating corrections to ensure convergence of the solution. This innovative approach allows for a detailed assessment of the structure's behavior over time.

Another significant patent is a method for determining a maximum acceptable alternating stress for a part subjected to cyclic loading. This method simulates constant loading on the part and assumes elasto-viscoplastic behavior. By using a Goodman diagram, Desmeure's method determines the maximum acceptable alternating stress based on the final static stress at a specific point. This patent is crucial for ensuring the reliability and safety of components under cyclic loads.
