Bending moments in free-swimming flagella.
The bending of a flagellum, such as the flagellum which forms the tail of a seaurchin spermatozoon, is the result of active mechanochemical processes occurring within the flagellum itself, which cause it to bend actively throughout its length (Gray, 1955; Machin, 1958). To understand how flagella operate, we must understand not only the mechanisms which generate bending, but also the control me...
متن کاملIn vivo horizontal bending moments on implants.
To date, transverse and vertical forces applied eccentrically to the axis of dental implants in the molar area during oral function have not been quantified. A specially designed load cell placed directly in the implant allowed for measurements of bending moments. Results of both load directions were compared to each other and to the loads applied vertically along the implant axis. The stress i...
متن کاملSpontaneous bending of pre-stretched bilayers
We discuss spontaneously bent configurations of pre-stretched bilayer sheets that can be obtained by tuning the pre-stretches in the two layers. The two-dimensional nonlinear plate model we use for this purpose is an adaptation of the one recently obtained for thin sheets of nematic elastomers, by means of a rigorous dimensional reduction argument based on the theory of Gamma-convergence (Agost...
متن کاملBending of bilayers with general initial shapes
Abstract We present a simple discrete formula for the elastic energy of a bilayer. The formula is convenient for rapidly computing equilibrium configurations of actuated bilayers of general initial shapes. We use maps of principal curvatures and minimum-curvature direction fields to analyze configurations. We find good agreement between the computations and an approximate analytical solution fo...
متن کاملChemically controlled bending of compositionally anisotropic microcylinders.
Soft materials that can undergo mechanical actuation in response to external stimuli, such as changes in temperature, light, pH value, or ionic strength, have attracted increasing attention because of their potential use as thinfilm actuators, smart sutures, and soft robots. These materials typically require specialty polymers, such as shape-memory polymers or use macroscopically layered films....
