Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges

The forms of U-shaped UHPFRC beams have not been investigated for the highway footbridge. Compared with the traditional section forms, the U-shaped UHPFRC beams can reduce the material consumption under the condition of providing the same bearing capacity. ...

Investigation of residual stresses in planar dissimilar magnetic pulse welds by neutron diffraction

Residual stresses are investigated for the first time in a dissimilar AA1050-DP450 steel magnetic pulse weld using neutron diffraction. Close to the joint interface, tensile residual stresses are observed in the Al sheet and compressive residual stresses a ...

Constitutive Modeling of Structural Steels: Nonlinear Isotropic/Kinematic Hardening Material Model and Its Calibration

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa

Numerical models of structural components that deteriorate primarily due to geometric instabilities under multiaxis cyclic loading are sensitive to both the assumed geometric imperfections and the nonlinear material model assumptions. Therefore, the accura ...

Experimental study of the strain patterned in 2D materials using thermal nanoimprint lithography

Johannes Mathis Valentin Lemonde

Since straining semiconductors can enhance the carriers’ mobility and thus improve optoelectronic properties, this project aims at determining whether t-NIL can be used in order to strain thin flakes of MoS2 out of the plane. In this approach, the thin fla ...

Giant hardening response in AlMgZn(Cu) alloys

William Curtin, Daniel John Gilles Marchand

This study presents a thermomechanical processing concept which is capable of exploiting the full industrial application potential of recently introduced AlMgZn(Cu) alloys. The beneficial linkage of alloy design and processing allows not only to satisfy th ...

Theory of twin strengthening in fcc high entropy alloys

William Curtin

Twinning in fcc High Entropy Alloys (HEAs) has been implicated as a possible mechanism for hardening that enables enhanced ductility. Here, a theory for the twinning stress is developed analogous to recent theories for yield stress. Specifically, the stres ...

Fatigue resistance of reinforced UHPFRC beams

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

This work investigates the fatigue resistance of reinforced Ultra High Performance Fiber Reinforced Cementitious composite (R-UHPFRC) beams with special consideration of steel rebar – UHPFRC interaction under tensile stresses due to bending. Experimental t ...

Shear behavior of single- and triple-thickness masonry panels strengthened by bed-joint structural repointing

Ricardo Javier Serpell Carriquiry

Bed-joint structural repointing is a widely used strengthening technique in historic masonry constructions, particularly in applications where the material appearance needs to be preserved. Despite its wide use, limited research is available on the effecti ...

Seeing and Touching the Mycomembrane at the Nanoscale

Georg Fantner, John McKinney

Mycobacteria have unique cell envelopes, surface properties and growth dynamics, which all play a part in the ability of these important pathogens to infect, evade host immunity, disseminate and to resist antibiotic challenges. Recent atomic force microsco ...

Inferring the flow properties of epithelial tissues from their geometry

Matthieu Wyart, Marko Popovic, Valentin Camille Druelle

Amorphous materials exhibit complex material properties with strongly nonlinear behaviors. Below a yield stress they behave as plastic solids, while they start to yield above a critical stress sigma(c). A key quantity controlling plasticity which is, howev ...
