RAILWAY AGE, MARCH 2023 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic that professionals in the railway industry have asked to learn more ...
Strain gages are sensing devices used in a variety of physical test and measurement applications. They change resistance at their output terminals when stretched or compressed. Because of this ...
Engineers have long used stress-strain curves to uncover a host of material properties. The curves are created by plotting the results of tensile strength tests of material samples, putting stress ...
Yield stress is the stress at which the breakdown of the structural frame occurs, and the related strain is the yield strain. Figure 1 represents the mechanical analogues depicting the process with ...
Strain measurement is imperative during prototype design and testing. Measuring strain ensures that materials perform as they should and that equipment is safe, functional, and durable. The resistive ...
To explain these features of strain-induced crystallization consistently with earlier theories, 13, 16, 17 the primitive mechanical model by James and Guth, 18 which assumes elastically effective ...
