Microstructural controls of anticrack nucleation in highly porous brittle solids

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Porous brittle solids have the ability to collapse and fail even under compressive stresses. In fracture mechanics, this singular behavior, often referred to as anticrack, demands for appropriate continuum models to predict the catastrophic failure. To ide ...

Dynamic study of contact damping in martensitic stainless steels using nano-indentation

Philippe Spätig, Hans-Peter Seifert

The study was undertaken to gain insight into the micro-mechanisms controlling plasticity at the micrometer scale of elastic-plastic metallic alloys. Dynamic nano-indentation tests, where a small harmonic force amplitude is superimposed during loading, ref ...

Micromechanical controls of mixed-mode anticrack nucleation in porous solids: application to snow failure

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Porous cohesive materials can fail and collapse under compressive stresses. This mechanical behavior is generally referred to as anticrack and in snow, it is at the origin of catastrophic avalanches. In this study, we investigate how the microstructure of ...

Universal features of anticrack nucleation in porous solids

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Characterizing the nucleation of anticracks in porous materials under compression is a great challenge and has been the subject of several investigationsin different fields, from earthquake science, rock mechanics to avalanche research[1]. Yet, the conditi ...

A High Resolution Digital Image Correlation Study under Multiaxial Loading

Helena Van Swygenhoven, Efthymios Polatidis, Wei-Neng Hsu

In this study, a miniaturized cruciform-shaped sample geometry which allows reaching high plastic strain under equibiaxial loading with reduced thickness at the test section is presented. The thinning method results in excellent surface quality that can be ...

Pore Size Manipulation in 3D Printed Cryogels Enables Selective Cell Seeding

Philippe Renaud, Arnaud Bertsch, Thomas Michael Braschler, Ariane Rochat, Amélie Barbara Hildegarde Béduer, Ludovic Serex, Aleksandra Filippova

Cryogels are macroporous materials that display remarkable properties, such as high pore interconnection, large surface to volume ratio, and high mechanical stability, making them good candidates for 3D cell culture. However, shaping cryogels remains chall ...

Morphology and interfacial strength of nonisothermally fusion bonded hard and soft thermoplastics

Pierre-Etienne Bourban, Rajasundar Chandran

Nonisothermally fusion bonded butt joints were prepared by overmolding thermoplastic elastomers (TPEs) onto isotactic polypropylene (iPP) inserts in order to investigate the effect of processing conditions on the bond strength and interfacial microstructur ...

Scaling description of non-local rheology

Matthieu Wyart, Jie Lin

The plastic flow of amorphous materials displays non-local effects, characterized by a cooperativity length scale xi. We argue that these effects enter in the more general description of surface phenomena near critical points. Using this approach, we obtai ...
