Richard G. Budynas is professor of mechanical engineering at Rochester Institute of Technology. He is author of a newly revised McGraw-Hill textbook, Applied Strength and Applied Stress Analysis, 2nd Edition. Ali M. Sadegh is a professor and the Founder and Director of the Center for Advanced Engineering Design at The City College of New York ...
Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers . A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus .
Marks' Standard Handbook for Mechanical Engineers is a comprehensive handbook for the field of mechanical engineering. Originally based on the even older German Hütte, it was first published in 1916 by Lionel Simeon Marks. In 2017, its 12th edition, published by McGraw-Hill, marked the 100th anniversary of the work. The handbook was translated ...
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of
L. M. Kachanov [5] and Y. N. Rabotnov [6] suggested the following evolution equations for the creep strain ε and a lumped damage state variable ω: ˙ = ˙ ˙ = ˙ where ˙ is the creep strain rate, ˙ is the creep-rate multiplier, is the applied stress, is the creep stress exponent of the material of interest, ˙ is the rate of damage accumulation, ˙ is the damage-rate multiplier, and is ...
