Mechanical-hydraulic interaction in the lining cracking process of pressure tunnels

Pressure tunnels are in operation subjected to internal water pressure. When the hoop tensile stress acting at the lining intrados exceeds the tensile strength of concrete, longitudinal cracks occur in the concrete lining. As a consequence of crack opening ...

Experimental Investigations and Probabilistic Strength Prediction of welded Double Lap Joints composed of Timber

Yves Weinand, Till Vallée, Bernhard Stamm, Benjamin Hahn

Wood-to-wood bonds obtained by means of friction welding are a relatively new type of connections holding high potential to compete with existing structural adhesives, since a load bearing bond is formed almost instantaneously. This paper addresses the que ...

Time course of flow-induced adaptation of carotid artery biomechanical properties, structure and zero-stress state in the arteriovenous shunt

Nikolaos Stergiopoulos

Numerous studies have provided evidence of diameter adaptation secondary to flow-overload. but with ambiguous findings vis a vis other morphological parameters and information on the biomechanical aspects of arterial adaptation is rather incomplete. We exa ...

Modeling size effects associated with tensile fracture initiation from a wellbore

Brice Tanguy Alphonse Lecampion

This paper investigates different tensile fracture initiation criteria on the plane-strain configuration of a defect-free openhole wellbore. It aims to model the effect of the internal pressurization of a wellbore drilled in the direction of one of the pri ...

Measurement of effective piezoelectric coefficients of PZT thin films for energy harvesting application with interdigitated electrodes

Paul Muralt, Andrea Mazzalai, Nachiappan Chidambaram

Interdigitated electrode (IDE) systems with lead zirconate titanate (PZT) thin films play an increasingly important role for two reasons: first, such a configuration generates higher voltages than parallel plate capacitor-type electrode (PPE) structures, a ...

Experimental investigation of collagen waviness and orientation in the arterial adventitia using confocal laser scanning microscopy

Michaël Unser, Nikolaos Stergiopoulos, Daniel Sage, Alessandra Griffa, Aristotelis Agianniotis, Jelle Tymen Christiaan Schrauwen

Mechanical properties of the adventitia are largely determined by the organization of collagen fibers. Measurements on the waviness and orientation of collagen, particularly at the zero-stress state, are necessary to relate the structural organization of c ...

Multiaxial yield behaviour of Al replicated foam

Andreas Mortensen, Raphaël Charvet, Etienne Combaz, Willy Dufour, Claudio Bacciarini

Multiaxial experiments are performed on replicated aluminium foam using a custom-built apparatus. The foam structure is isotropic, and features open monomodal pores 75 mu m in average diameter. Plane stress (sigma(1), sigma(2), sigma(3) = 0) and axisymmetr ...

An Isotropic Auxetic Structural Network with Limited Shear Stiffness

Alessandro Spadoni

The chiral lattice is a unique structural network not symmetric to its mirror image, and with a negative Poisson’s ratio. Previous investigations have considered this structural network for the design of superior structural components with sandwich constru ...

Numerical modelling and strength prediction of welded double lap joints made of timber

Yves Weinand, Till Vallée, Bernhard Stamm, Benjamin Hahn

Welding of wood is a relatively new method of joining load bearing elements, which holds the potential to compete with structural adhesion, since it allows for an almost instantaneous bond. First experimental and numerical investigations showed that failur ...

On the Mutual Effect of Viscoplasticity and Interfacial Damage Progression in Interfacial Fracture of Lead-Free Solder Joints

John Botsis, Joël Cugnoni, Milad Maleki

The main goal of this paper is to shed light on the effect of strain rate and viscoplastic deformation of bulk solder on the interfacial failure of lead-free solder joints. For this purpose, interfacial damage evolution and mode I fracture behavior of the ...
