Mitochondrial activity detected by cantilever based sensor

Giovanni Dietler, Sandor Kasas, Petar Stupar, Wojciech Chomicki

Our team recently demonstrated that cantilever based devices can detect signature of life in a chemistry independent manner. In this technique, the organism of interest is attached onto a classical AFM cantilever. If alive, it induces nanometre scale oscil ...

Studies on Traction Separation Relations in Fracture of Layered Composites : Experiments and Modeling

Georgios Pappas

Layered fiber reinforced composite materials are prone to fracture in planes parallel to the direction of fibers leading to extensive delamination or intralaminar fracture. This phenomenon of crack propagation is frequently accompanied by significant incre ...

A multi-scale based cohesive zone model for the analysis of thickness scaling effect in fiber bridging

John Botsis, Luis Pablo Canal Casado

A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever Beam ...

MEMS cantilever sensor array oscillators: Theory and experiments

Yusuf Leblebici, Ulas Adiyan

This paper demonstrates that an array of cantilever sensors can be operated simultaneously at resonance using a single actuator and a single photodetector. Self-sustained oscillations (SSOs) of cantilevers can be achieved in a feed-back loop using gain sat ...

Large scale fiber bridging in mode I intralaminar fracture. An embedded cell approach

John Botsis, Georgios Pappas, Luis Pablo Canal Casado

Fiber reinforced composites can develop large scale bridging upon mode I fracture. This toughening mechanism depends on the constituents and the geometry of the specimen, and is especially important in unidirectional laminates when fracture is parallel to ...

Effects of large scale bridging in load controlled fatigue delamination of unidirectional carbon-epoxy specimens

John Botsis, Joël Cugnoni, Ebrahim Farmand Ashtiani

Fatigue delamination growth in composites is accompanied by large scale bridging (LSB) that yields important toughening effects. However, the extent of this mechanism depends on the laminate geometry rendering its modeling a challenging task. This work pre ...
