This article starts with the analysis of contact between laser processing bionic brake drum unit body and pad performs force based on elastic mechanics mechanics. By using Preston equation, wear caused by is obtained, as well relevant factors influence rule which affects are found. During body, in order to reduce pad, height should be minimized. Besides, light intensity at centre spot reduced, ...

A statistical distribution for an adiabatically isolated body is proposed and its temperature defined as a function of given energy. It obtained result the generalization ensemble oscillators, in which probability proportional to time motion on each small section oscillator trajectory phase space. This makes it possible explain thermoelastic effect --- dependence deformation under adiabatic mec...

Concrete is a material whose performance is governed by the subtle interaction of its cohesive and frictional constituents. Since the theories of plasticity, damage mechanics, and fracture mechanics cannot, by themselves, capture both of these phenomena, a novel constitutive model is proposed which combines the theories of plasticity and damage mechanics in a multi-surface formulation. Synthesi...

BACKGROUND One of the preventive strategies for chronic low back pain among operating room nurses is instructing proper body mechanics and postural behavior, for which the use of the Transtheoretical Model (TTM) has been recommended. METHODS Eighty two nurses who were in the contemplation and preparation stages for adopting correct body posture were randomly selected (control group = 40, inte...
