We compare the performances of the templates defined by three different types of approaches: traditional post-Newtonian templates ~Taylor approximants!, ‘‘resummed’’ post-Newtonian templates assuming the adiabatic approximation and stopping before the plunge (P approximants!, and further ‘‘resummed’’ postNewtonian templates going beyond the adiabatic approximation and incorporating the plunge w...

We compare the performances of the templates defined by three different types of approaches: traditional post-Newtonian templates (Taylor-approximants), “resummed” post-Newtonian templates assuming the adiabatic approximation and stopping before the plunge (P-approximants), and further “resummed” post-Newtonian templates going beyond the adiabatic approximation and incorporating the plunge with...

Flexible flapping wings have garnered a large amount of attention within the micro aerial vehicle (MAV) community: a critical component of MAV flight is the coupling of aerodynamics and structural dynamics. This paper presents a computational framework for simulating shell-like wing structures flapping in incompressible flow at low Reynolds numbers in both hover and forward flight. The framewor...

the aim of this article is study of tool plunge depth (tpd) effects on mechanical properties of friction stir welding of aa1100 aluminium alloy to a441 aisi steel. for this purpose the 0.1, 0.2, 0.4, and 0.6 mm tpd selected and other welding parameters kept constant. the results shows that the frictional heat increases and stir zone grain size decreases with increasing tpd at both base metals. ...

Influences of two different sample preparation methods, mechanical polishing and plunge cutting, on nanoindentation behavior of a Zr-based bulk metallic glass were studied. Mechanical polishing suppresses the serrated flow but promotes the creep. In contrast, plunge cutting promotes the serrated flow but suppresses the creep. However, hardness and elastic modulus obtained from these two methods...
