How to Make Elastomers Piezoelectric?
Piezoelectrics play a significant role in modern electronics and electric devices. Thermal or mechanical stress on such materials induces a change in polarization generating an electric response, which is the sole effect of why they are so interesting. How ...
WILEY2023Multi-scale characterization and modeling of notched strength and translaminar fracture in hybrid thin-ply composites based on different carbon fiber grades
Owing to their high specific stiffness and strength, Carbon Fiber Reinforced Composites (CFRP) are ideal candidates for the development of lightweight high-performance structures. Within this family, thin-ply composites allow for wider design freedom and p ...
EPFL2023Influence of Fiber Orientation on the Elastic Limit Tensile Stress of UHPFRC
Eugen Brühwiler, Emmanuel Denarié, Jian Zhan
The elastic limit tensile stress of UHPFRC is governed by contributions of the cementitious matrix and the fibrous skeleton. This paper finds that fiber orientation has significant influence on the matrix tensile strength of UHPFRC, while this is not consi ...
2023Bounding the localized to ductile transition in porous rocks: implications for geo-reservoirs
Marie Estelle Solange Violay, Gabriel Gérard Dominique Meyer
Porous rocks have long been the focus of intense research driven by their importance in our society as host to our most essential resources (oil, gas, water, geothermal energy, etc), yet their rheology remains poorly understood. With increasing depth, poro ...
2023Simple shear extrusion versus equal channel angular pressing: A comparative study on the microstructure and mechanical properties of an Mg alloy
Roland Logé, Cyril Cayron, Aryan Rezaei Rad
Two severe plastic deformation (SPD) techniques of simple shear extrusion (SSE) and equal channel angular pressing (ECAP) were employed to process an extruded Mg -6Gd -3Y -1.5Ag (wt%) alloy at 553 K for 1, 2, 4 and 6 passes. The microstructural evolutions ...
KEAI PUBLISHING LTD2023Reliability analysis and partial safety format calibration considering the characteristics of the resistance of reinforced concrete structures
Every engineering calculation is an approximation of reality, with inevitable uncertainties involved. This fact implies that a reliability verification accounting for the uncertainties is a necessary step in the design and assessment of structures. Nowaday ...
EPFL2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Elastic limit tensile stress of UHPFRC: Method of determination and effect of fiber orientation
Eugen Brühwiler, Emmanuel Denarié, Jian Zhan
This paper discusses the influence of fiber orientation on elastic limit tensile stress of ultra-high performance fiber reinforced cementitious composites (UHPFRC). An original model relating elastic limit tensile stress to fiber orientation is proposed, a ...
2023Drained Clay-Pipe Interface Resistance at Low Normal Stresses and Elevated Temperatures
Offshore pipelines that transport hydrocarbons under high pressure and high temperature are usually thermally insulated to maintain an elevated temperature and prevent any heat loss to the surroundings. However, the temperatures at the outer-wall of the pi ...
AMER SOC CIVIL ENGINEERS2023Computational Design of Flexible Planar Microstructures
Mark Pauly, Tian Chen, Francis Julian Panetta, Christopher Brandt, Jean Jouve
Mechanical metamaterials enable customizing the elastic properties of physical objects by altering their fine-scale structure. A broad gamut of effective material properties can be produced even from a single fabrication material by optimizing the geometry ...
