This paper presents the design and prototyping of an inherently compliant lightweight hand mechanism. The hand mechanism itself has 15 degrees of freedom and five fingers. Although the degrees of freedom in each finger are coupled, reducing the number of independent degrees of freedom to 5, the 15 degrees of freedom of the hand could potentially be individually actuated. Each joint consists of ...

Conducting damage diagnostics on stiffened panels is commonly performed using a single SHM technique. However, each technique has both its strengths and limitations. Rather than straining the expansion of techniques going beyond their intrinsic capacities, these limitations should instead be considered in application. In this work, we propose novel fusion-based methodology between data from two...

Variable angle tow laminates (VAT) and stiffeners are known to redistribute the in-plane load distribution tailor buckling mode shapes, respectively, for improving structural performance. To leverage benefits of using VAT in practical applications, present paper, we discuss maximization conducted a stiffened laminated plate with central cutout considering laminate manufacturing constraints. Thr...

1 Graduate Assistant 2 Associate Professor, Corresponding author ABSTRACT This research describes a novel ceramic thin-small-outline package (C-TSOP) to meet the thermal performance and long-term reliability considerations of today’s low-pin-counts and high-performance electronic devices, especially for memory devices. To improve the disadvantages of molding compound and to simplify fabrication...

Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated with large-scale rolled beam and built-up specimens having yield strength of 345 to 760 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating t...

In this study the basic engineering principles, goals and constraints are all combined to fuzzy methodology and applied to design optimally sandwich panel circular plate roofs for large vessels. These panels are made up of two stiff, strong veneer skins separated by vertical and peripheral stiffener plates. Advantages are high strength and lightweight and sustainability. In the present approach...
