Electromechanical resonant ice protection systems: numerical investigation through a phase-field mixed adhesive/brittle ...
Electromechanical resonant de-icing systems provide a low-energy solution against ice accumulation on aircraft. Recent researches show a growing interest towards these systems in the context of more electrical aircraft. Electrome-chanical de-icing systems consists in electric actuators producing stress within the ice, through micro-vibrations of th...
Efficacité du renforcement par composites collés vis-à-vis de la propagation de fissures de fatigue pour une application...
La fatigue représente la deuxième cause d'endommagement des structures métalliques anciennes après la corrosion. Celle-ci se manifeste par l'apparition de fissures, dans les zones fortement sollicitées présentant des concentrations de contraintes importantes, et peut mener à terme à la ruine de l'ouvrage. Dans le cas des structures métalliques anci...
Two Dimensional modelling of electrothermal ice protection systems
Icing has since long been identified as a serious issue in the aeronautical world. Ice build up, due to the presence of supercooled water droplets in clouds, leads to degradation of aerodynamic and/or air intake performances, among other undesirable consequences. Hence aircraft manufacturers must comply with certifications and regulations regarding...
How Tough Is Brittle Bone? Investigating Osteogenesis Imperfecta in Mouse Bone
...
The multiscale hierarchical structure of bone is naturally optimized to resist fractures. In osteogenesis imperfecta, or brittle bone disease, genetic mutations affect the quality and/or quantity of collagen, dramatically increasing bone fracture risk. Here we reveal how the collagen defect results in bone fragility in a mouse model of osteogenesis...

The 30th MPA-seminar on ''Safety and Availability in Energy Engineering'' was held in conjuction with the 9th German-Japanese Seminar. The 52 contributions were published in two volumes. Volume 1 contains the contributions to the following sessions: fracture mechanics, fatigue, welding, environmental impact and European research projects. Volume 2 ...
ETM format for creep deformation parameters
Parameters for the correlation of creep deformation and crack extension behavior are developed from principles that assume the commonality of all deformation forms. An assumption is made that the relationship between the force, crack length and deformation parameters has a separated format that is common for of all types of deformation. This allows...
