Darvin’s theory of evolution is widely held concept which states that all the life has evolved from a common ancestor: fruits, animals, trees, flowers. During the gradual process of evolution, beneficial random genetic mutations in […]
From the first friction quantitative experiments by Leonardo da Vinci (1452-1519) and most notably from our everyday life experience, it is known that there is an inevitable force opposing to the initiation of motion of […]
Friction is everywhere around us, working against motion of cars, airplanes, their engines, wind mills and other devices causing wear and decreasing their energy and overall performance efficiency. However, there exists a certain state, called […]
Friction rises when bodies come to contact and start relative sliding. This phenomenon occurs in many mechanical systems and it is estimated that over 30% of the fuel in cars is consumed to overcome friction. […]
Imagine a new type of tyres whose structure has been designed to have greater adhesion on the road. Quite a timely discussion during the long winter nights. French physicists have now developed a model to […]
Society of tribology and lubrication engineers announced Contact Mechanics Challenge. Dr. Martin Müser initiated a competition in calculation of a real contact area. He has already results of his own calculation and challenges other groups […]
