Donald G. Rubenstein,Carol Zaheron. In the recent years, these techniques and methods have improved dramatically, allowing considerably more accurate measurement of displacement and strain field in the laboratory specimens. It is time to have a second look, with these new glasses, at some decades-old results, to assess what can be confirmed and what should be reconsidered.作者: Diatribe 時(shí)間: 2025-3-22 06:06
