Free Download Transient Effects in Friction: Fractal Asperity Creep By Andreas Goedecke (auth.)
2013 | 197 Pages | ISBN: 3709115051 | PDF | 6 MB
Transient friction effects determine the behavior of a wide class of mechatronic systems. Classic examples are squealing brakes, stiction in robotic arms, or stick-slip in linear drives. To properly design and understand mechatronic systems of this type, good quantitative models of transient friction effects are of primary interest. The theory developed in this book approaches this problem bottom-up, by deriving the behavior of macroscopic friction surfaces from the microscopic surface physics. The model is based on two assumptions: First, rough surfaces are inherently fractal, exhibiting roughness on a wide range of scales. Second, transient friction effects are caused by creep enlargement of the real area of contact between two bodies. This work demonstrates the results of extensive Finite Element analyses of the creep behavior of surface asperities, and proposes a generalized multi-scale area iteration for calculating the time-dependent real contact between two bodies. The toolset is then demonstrated both for the reproduction of a variety of experimental results on transient friction as well as for system simulations of two example systems.

The study of sliding friction is one of the oldest problems in physics, and certainly one of the most important from a practical point of view. Low-friction surfaces are in increasingly high demand for high-tech components such as computer storage systems, miniature motors, and aerospace devices. It has been estimated that about 5% of the gross national product in the developed countries is "wasted" on friction and the related wear. In spite of this, remarkable little is understood about the fundamental, microscopic processes responsible for friction and wear. The topic of interfacial sliding has experienced a major burst of in terest and activity since 1987, much of which has developed quite independently and spontaneously. This volume contains contributions from leading scientists on fundamental aspects of sliding friction. Some problems considered are: What is the origin of stick-and-slip motion? What is the origin of the rapid processes taking place within a lub at low sliding velocities? On a metallic surface, is the rication layer electronic or phononic friction the dominating energy dissipation pro cess? What is the role (if any) of self-organized criticality in sliding friction? How thick is the water layer during sliding on ice and snow? These and other questions raised in this book are of course only part ly answered: the topic of sliding friction is still in an early state of development.

Free Download Eve Driver, "What We Can’t Burn : Friendship and Friction in the Fight for Our Energy Future"
English | ISBN: 1958510033 | 2024 | 200 pages | EPUB | 1361 KB
When they met as juniors at Harvard, Kenyan clean energy entrepreneur Tom Osborn and American climate writer Eve Driver did not get along. While a trip to Kenya over winter break sparked an unlikely friendship, it was tested back on campus amid the college’s fossil fuel divestment campaign–which Eve joined, and Tom opposed. In fresh voices that are raw, funny, and lyrical, the two take turns telling the story of their rocky but transformative friendship, which gripped and changed both of their minds.

English | ASIN: B0CRXMRZYJ | 2024 | MP3@64 kbps | ~06:25:00 | 182 MB
Why do some businesses "fail to scale"? Smooth Scaling offers a clear diagnosis, along with twenty practical Rituals to boost your organization’s performance and achieve frictionless growth.
Smooth Scaling addresses the most pervasive and least-understood fail point that threatens to kneecap even the best-laid scaling plan: organizational friction. Expert Rob Bier reveals why organizational frictions take hold as you grow and how they slow your company down.
These growth pains are both predictable and preventable, yet they almost always take leaders by surprise. But it doesn’t have to be this way. Until now, there’s been no resource to guide executives through this challenge. As a result, they end up playing "Whack-a-Mole," reacting to a never-ending stream of organizational, team, and people problems one at a time-only for new ones to crop up. Smooth Scaling addresses this gap, presenting a proven approach based on real-life experience and application.

The definitive guide to eliminating the forces that make it harder, more complicated, or downright impossible to get things done in organizations. Find out why Adam Grant says, "If every leader took the ideas in this book seriously, the world would be a less miserable, more productive place." Every organization is plagued by destructive friction. Yet some forms of friction are incredibly useful, and leaders who attempt to improve workplace efficiency often make things even worse. Drawing from seven years of hands-on research, The Friction Project by bestselling authors Robert I. Sutton and Huggy Rao teaches readers how to become "friction fixers." Sutton and Rao kick off the book by unpacking how skilled friction fixers think and act like trustees of others’ time.
