Latest Developments in Modeling and Characterization of Joining Metal Based Hybrid Materials

Abstract

Advanced materials consist of several materials systems that exhibit complementary properties for multipurpose applications. Joining of dissimilar materials is a critical and challenging advanced manufacturing technique to develop novel hybrid materials with properties fully transferred. The "bonding strength" of a joint is crucial for its integrity and performance. The bonding strength is affected by a range of parameters that can be better understood, controlled, and optimized via both experimental and analytical approaches. In this paper, the authors review the theoretical and experimental studies of the interface inside several metal based composites. The scope includes interface bonding's critical parameters, characterization techniques of joining processes, potential applications, and their future perspectives. The review is significant to develop advanced manufacturing techniques for heterogeneous materials and to design innovative heterogeneous systems for various medical, electrical, electronics, industrial, and other daily life applications that involve the broad range of "joining" processes.

Automatic Expanding Mandrel with Air Sensing Device: Design and Analysis

“…As shown in Figure 12, the centrifugal force F i of the element "i" is computed as a function of the rotational speed n, the mass m i and the radius of the mass center r ci , where i = cn, pt or pn (which represent transmission system, piston, and collet, respectively), by Equation (19).…”

“…As the joining of different materials is influenced by a range of parameters which are better recognized, monitored and optimized through both experimental and analytical methods [18,19], this paper presents an analytical model for determining the dynamic clamping force of the proposed expanding mandrel design based on solid rigid theory, elasticity and mechanical contact. The proposed analytical model takes stiffness behaviors into account and was implemented over Matlab.…”

Theoretical Design Strategies, Strengths, Costs, and Environmental Impacts of Triple Composite Beams Utilizing Glass Compressive Reinforcement

“…The presence and necessity of bond strength are noted here, the primary contribution of this work is the use of glass as compressive reinforcement in macro-scale composites. The direct approach to modeling bonding strengths is to examine the geometry between elements [14]. Accordingly, what is unique to compressive forces when dealing with composites is an increase in frictional forces that occur at the interface of two materials placed in compression.…”

“…An additional aspect is that beams that have glass throughout their depth tend to be significantly more expensive due to the relatively high cost of glass per unit area. The interactions between dissimilar materials are where new properties for composites are found [14], though the bonding strength does pose challenges. The presence and necessity of bond strength are noted here, the primary contribution of this work is the use of glass as compressive reinforcement in macro-scale composites.…”

Self-Piercing Riveted Joint of Vibration-Damping Steel and Aluminum Alloy

“…However, it is challenging to join the vibration-damping steels to aluminum alloys, since conventional fusion joining methods for metals, such as resistance spot welding [3][4][5] and laser welding [6][7][8], are not applicable to aluminum alloys and steel dissimilar joints due to their large 2 of 14 difference in thermo-mechanical properties and Fe-Al-based brittle intermetallic compounds (IMC) in the weld area [9][10][11]. Diffusion bonding can be used to join dissimilar metals; however, the suitability of diffusion bonding has been limited to highly reactive materials (titanium, beryllium, or zirconium) so far [12]. Therefore, non-fusion and non-diffusion joining methods, including adhesive bonders or mechanical fasteners, have been mainly considered for such dissimilar joints.…”
