An experimental study to characterize properties controlling delamination of paperboard is presented. The normal and shear traction–separation laws are measured evaluated using a double cantilever beam (DCB) split (SCB) specimen. DCB-experiments provides separation data in good agreement with results alternative techniques. From the data, both fracture resistance obtained. A length parameter in...

Design and modelling of MEMS test structures for the analysis of fatigue damage occurring in oscillating microstructures is presented. Finite Element models are realized to design specimen shapes and electro-mechanical actuation parameters. Two different structural geometries are defined to obtain both traction and shear tensile specimen actuations through the actuation of out-of-plane movable ...

Though much research has been conducted regarding traction of tires in soft granular terrain, little empirical data exist on the motion of soil particles beneath a tire. A novel experimentation and analysis technique has been developed to enable investigation of terramechanics fundamentals in great detail. This technique, the Shear Interface Imaging Analysis Tool, provides visualization and ana...

Though much research has been conducted regarding traction of tires in soft granular terrain, little empirical data exist on the motion of soil particles beneath a tire. A novel experimentation and analysis technique has been developed to enable detailed investigation of robot interactions with granular soil.

[1] The shear tractions that mantle flow exerts on the base of Earth’s lithosphere contribute to plate-driving forces and lithospheric stresses. We investigate the sensitivity of these tractions to sub-lithospheric viscosity variations by comparing shear tractions computed from a mantle flow model featuring laterally-varying lithosphere and asthenosphere viscosity with those from a model with l...

a 5th order shear deformation theory considering transverse shear deformation effect as well as transverse normal strain deformation effect is presented for static flexure   analysis of simply supported isotropic plate. the assumed displacement field accounts for non-linear variation of in-plane displacements as well as transverse displacement through the plate thickness. the condition of zero ...

OBJECTIVE To determine the influence of mechanical intermittent cervical traction on the autonomic system. DESIGN Prospective, cases series study. SUBJECTS Sixteen healthy volunteers without contraindications for cervical traction. METHODS Subjects received mechanical intermittent cervical traction in a sitting position under two traction forces (10% and 20% of total body weight). Electr...

Stick insects (Carausius morosus) have two distinct types of attachment pad per leg, tarsal "heel" pads (euplantulae) and a pre-tarsal "toe" pad (arolium). Here we show that these two pad types are specialised for fundamentally different functions. When standing upright, stick insects rested on their proximal euplantulae, while arolia were the only pads in surface contact when hanging upside do...
