Mike Ryland presented the design of a dense memory module connector. Some key points:
- The connector uses a tapered beam contact design to uniformly distribute stress along the contact length and minimize local stress concentrations. Simulation found the design can withstand the target 5.3 gram normal force per contact.
- Prototypes of the tapered beam contacts were manufactured and tested, showing the design had minimal permanent deformation after a 0.015mm deflection.
- The complete DMM module design houses the pin-socket-BGA interconnect array and includes features for thermal management within a 1U chassis.
- Tolerance analysis and simulations were performed to validate the design could meet requirements with the expected variances
Effect of wind load on tall buildings in different terrain categoryeSAT Journals
Abstract Wind is a perceptible natural motion of air relative to earth surface ,especially in the form of air current blowing in a particular direction. The major harmful aspect which concern to civil engineering structures is that, it will load any and every object that comes in its way. Wind blows with less speed in rough terrain and higher speed in smooth terrain . This paper presents displacement accour in different storey due to wind in different terrain category. Three models are analyse using ETABS 2015 package. Present works provides a good source of information about variation in deflection as height of model changes and percentage change in deflection of same model in different terrain category. Keywords: TG-1, TG-2, TG-3, TG-4, ETABS 2015, Deflection, %age of deflection

The various types of Impact , Crash Tests, Shock loading and the associated standards required to evaluate the various structures or vehicles for impact, shock and/or crashworthiness are discussed here.
Fatigue and fracture behavior of additively manufactured metals after heat tr...TAV VACUUM FURNACES
Additive Manufacturing (AM) is any of various processes of making three-dimensional solid objects from a digital file.
Unlike subtractive manufacturing methods that start with a solid block of material and then cut away the excess to create a finished part, additive manufacturing builds up a part (or features onto parts) layer by layer from geometry described in a 3D design model.
For many decades, AM processes have been used for rapid prototyping. Over the last few years, additive manufacturing has gained incredible interest in all industry facets: from aerospace applications to simple one-off consumer home builds. This technology has immense versatility and flexibility, due to its ability to create complex geometries with customizable material properties.
Discover how the additive manufacturing processing of metals makes it possible to design and build lightweight parts in real time and understand potential of heat treatments in vacuum for 3D printed parts.
Design and Additive Manufacturing Considerations for Liquid Rocket Engine Dev...MartinVanDenBerghe1
The effective use of additive manufacturing requires careful design methods, specifically targeting subsequent post-processing and machining efforts. This paper covers the design, manufacturing and post-processing considerations that went into the development of an additively manufactured, bi-propellant, pressure-fed liquid rocket engine. Special considerations include initial constraints on engine design related to DMLS printing requirements, as well as post-printing ultrasonic cleaning, heat treatment, wire EDM and machining processes. Unexpected design related challenges and complications were found and solved throughout the manufacturing process. Solutions, such as developing custom machining tools, were devised to overcome these difficulties and ultimately allowed the completion of a hot-fire readiness testing campaign. This project was designed and completed by the student-led Liquid Propulsion Laboratory at the University of Southern California.
