A novel finite element for modeling a fastener in a lap joint assembly
Foster, Brian D. (Wichita State University, 2014-12)This work documents the development of a novel finite element. This element introduces parameters that allow more accurate modeling for the specific application of mechanically fastened lap joints. The research here bridges ... -
Buckling, postbuckling and progressive failure analysis of hybrid composite shear webs using a continuum damage mechanics model
Herrero, Javier (Wichita State University, 2007-12)This dissertation presents an innovative analysis methodology to enhance the design of composite structures by extending their work range into the postbuckling regime. This objective is accomplished by using the numerical ... -
Characterization of adhesives at room and elevated temperatures
Nedukanjirathingal, Santhosh Kumar (2006-07)Recent interest in advanced materials has paved the way for exploring joining options besides the traditional mechanical or thermal methods such as riveting or welding. Because of the availability of highly advanced ... -
Development of a fastener element in a lap joint with plates
Ly, Hoa T. (Wichita State University, 2018-05)The application of joints or other forms of connections are often seen in large assembled structures. When it comes to model joints in FEA software, engineers have some difficult decisions to make. Modeling joints using ... -
Finite element and analytical models for load transfer calculations for structures utilizing metal and composites with large CTE differences
Meka, Uday Sankar (2007-05)Large composite structures have been increasingly used in the aviation industry. In order to achieve higher fuel efficiency, the use of light-weight, high-strength composite materials, such as carbon/epoxy, needs to be ... -
Finite element application for strength analysis of scarf-patch-repaired composite laminates
Chou, Shih-Pin (2006-12)The composite scarf joint configuration was utilized to simulate scarf-patch-repaired composite panels. An adhesive bonded scarf (tapered) joint was selected due to less peeling and shear stress over the bondline than with ... -
Optimization of analysis using VCCT’s for prediction of failure initiation of adhesively bonded joints
Martino, Silvio Damian (Wichita State University, 2011-12)Adhesively bonded joints are used on numerous applications involving light-weight composite materials. Consequently, the successful modeling and subsequent analysis of bonded joints involving more than one adherend ... -
Strain energy release rate analysis of adhesive-bonded composite joints with a prescribed interlaminar crack
Chadegani, Alireza (Wichita State University, 2008-05)Composite materials together with adhesive-bonding have been increasingly used in the aviation industry. Delamination is among the critical failure modes in fiber-reinforced laminated composite structures including ...
