Combined computational-experimental investigation of residual stresses and pre-cracking in mode I behaviour of thick adhesively bonded GFRP composite joints

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

This paper presents a novel Finite Element (FE) simulation approach to examine the mode I fracture of thick adhesive joints used particularly in the trailing edge of the wind turbine blades. The approach involved FE models of the DCB specimens focusing on ...

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti-6al-4v

Roland Logé, Cyril Cayron, Jamasp Jhabvala, Eric Boillat, Mathijs Pieter van der Meer, Reza Esmaeilzadeh, Lucas Maximilian Schlenger, Seyed Amirmohammad Jamili, Junfeng Xiao

Laser Powder Bed Fusion (LPBF) stations mostly use lasers with a Gaussian beam intensity distribution, as it has advantages like small divergence and high ability to be focused. This distribution creates significant thermal gradients leading to high coolin ...

ScoreNet: Learning Non-Uniform Attention and Augmentation for Transformer-Based Histopathological Image Classification

Jean-Philippe Thiran, Seyedbehzad Bozorgtabar, Thomas Grégoire Stegmüller, Antoine Jérôme Spahr

Progress in digital pathology is hindered by high-resolution images and the prohibitive cost of exhaustive localized annotations. The commonly used paradigm to categorize pathology images is patch-based processing, which often incorporates multiple instanc ...

Intermittent tensile deformation of silver microcastings: Influence of the strain rate

Andreas Mortensen, Luciano Borasi

We compare the uniaxial tensile behavior of mu m-scale cast silver tensile specimens at strain rates of 10(-3 )s(-1) and 2 s(-1) to find no major impact of the strain rate on either of the flow stress, work hardening, or strain to fracture. Plastic deforma ...

Influence of dynamic congestion with scheduling preferences on carpooling matching with heterogeneous users

Nikolaos Geroliminis, Patrick Stefan Adriaan Stokkink

Carpooling is an efficient measure to fight car ownership and reduce vehicle kilometres travelled. By individuals sharing their commutes, vehicle occupancy increases and congestion is reduced. We develop a dynamic ADL (Arnott, de Palma, Lindsey)-Vickrey ap ...

A Lagrangian decomposition scheme for choice-based optimization

Michel Bierlaire, Meritxell Pacheco Paneque

Choice-based optimization problems are the family of optimization problems that incorporate the stochasticity of individual preferences according to discrete choice models to make planning decisions. This integration brings non-convexity and nonlinearity t ...

Considering snow depositions and transport mechanisms in meteorological analysis of predicting snow loads on buildings

Michael Lehning

The meteorological conditions determine snow evolutions on and around buildings. Those climatic impacts have been independently considered in the current design codes of buildings, namely the wind pressure and the snow load. But snow load estimates are onl ...
