Mechanical engineering

Establishing a test-calculation dialogue for shear tests on masonry triplets.

The development of digital image correlation techniques, particularly in the field of masonry, has allowed for the detection of crack evolution in joints and blocks over time. Recent studies further demonstrate the potential of these techniques for…

Test optimization for the identification of elastic and orthotropic parameters

Identifying constitutive parameters for composite materials often means relying on many tests, particularly when dealing with anisotropic models. To be able to design shorter test campaigns, this work aims to identify as many elastic parameters as…

Boundary conditions and constitutive parameter identification

This study proposes a method to determine boundary conditions outside of the full-field measured area and calibrate elastoplastic parameters, allowing for a simulation of the full specimen geometry. This method has been compared to traditional…

Development of a simplified model for the analysis of bolted assemblies under extreme loadings

Bolted joints are very common in mechanical engineering, particularly in aeronautics(for example, 3,000,000 joints on an A380). Their optimization requires elaborate designstrategies that take into account the various phenomena involved in…

Theoretical modeling of the behavior of woven fabrics subjected to stabbing

This work presents an analytical model of the behavior of fabrics subjected to stabbing. It permits to take into account fiber slidings, frictions between fibers and a knife with a complex geometry during perforation. This model is based on the…
