Welding characteristics and structures of same and different metal specimens using ultrasonic complex vibration welding equipments
Ultrasonic complex vibration welding of same and different metal specimens and structures of the welded area are studied using several complex vibration welding systems, scanning and transmission electron microscopes (SEM and TEM). Ultrasonic welding can weld various metal directly using vibration and static clamping pressure. The welding area is limited very narrow layer and can weld different...
متن کاملReprint: Finite Element Modeling of Vibration Stress Relief after Welding
A finite element model was developed to simulate the vibratory stress relief after welding. Both resonant and nonresonant vibrations can relieve residual stresses in welded structures by creating plastic deformation around the weld area. For the non-resonant vibration, the stress reduction strongly depends on the vibration amplitude. For the resonant vibration, the vibration frequency is the ke...
متن کاملVibration Power Flow: A Critical Review
Prediction and measurement of vibration power flow in structures are both important for locating vibration sources and sinks and for confirming vibration propagating paths. From the point of view of noise and vibration control in industries, the method is very important for practical reasons. Consequently, it is essential to address the state of the art of the method, its effectiveness and limi...
متن کاملترجمه بخشی از کتاب "critical readings in translation studies"
چکیده در دنیای پیچیده ی امروز، تغییرات زیادی در زندگی بشری در حال وقوع اند و شاهد رقابت های بسیار فشرده ی جوامع در دستیابی به فناوری برتر و قدرت بیشترهستیم. به نظر می رسد که فرد وجامعه مجبورند به طریقی در وضعیت خویش دگرگونی ایجاد کنند تا از قافله ی علم، فناوری، و پیشرفت عقب نمانند. رشته مطالعات ترجمه نیز از این قاعده مستثنا نیست. علی رغم وسعت روز افزون پژوهش در این حوزه و میان رشته ای بودن مطال...
Critical Conditions for Phytoplankton
We motivate and analyze a reaction-advection-diiusion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. The light intensity decreases with depth due to absorption by water and phytoplankton. Phytoplankton is transported by turbulent diiusion in a water column of given depth. Furthermore, it might be sinking ...
