Unitary Approach of Mechanical Structures and Living Organisms Lifetime

Abstract:

At present, the cumulation of stress effects that are similar in nature may be carried out for engineering structures and living organisms only when the behavior of matter is linear. In reality, matter behaves nonlinearly, stresses are often of a different nature (electrical, magnetic, chemical, mechanical, thermal, etc.). In essence, the lifetime of engineering structures and living organisms can be treated in the same way. We have put forth a system of assessing lifetime based on dimensionless concepts. There are shown, in charts based on dimensionless quantities, the factors that determine lifetime. A parallel is drawn between the process of deterioration and irreversibility. Reference is made to such facts as: - with the nonlinear behaviour of matter the total effect is different from the sum of partial effects; - the synergistic effect is determined by some behavioral particulars of matter; - the influence of matter deterioration on lifetime; - the possibility of an integrated treatment in calculating lifetime in engineering structures and living organisms based on the behaviour of matter when under load. The analysis made it possible to comprehend how - in general - lifetime is generated. Keywords: lifetime of mechanical structures, lifetime of living organisms, deterioration, critical participation, synergy
