...Amster Howard The Iowa formula was published by Professor M. G. Spangler of Iowa State Univ. in 1941 to predict the deflection of buried flexible pipe. In the equation, he used the term “deflection lag” to describe the increase in flexible pipe defection after the maximum load was reached over...

...RM Bennett, Ph.D, PE; WM McGinley, Ph.D, PE; J Bryja, M.Sc, SE This paper examines issues related to deflection criteria for masonry beams. Masonry walls supported by beams and lintels act compositely with the beam. As the height of the masonry wall increases, the behavior becomes more like...

... the specimen, and the force-deflection and energy-deflection curves. This paper recounts the early history of instrumented impact testing, and shows that it also extends back over 100 years. In fact, the earliest known paper on instrumented impact testing predates the first pendulum test machine publication...
