QUALITATIVE EVALUATION OF CFRP-CONCRETE BOND USING NON-DESTRUCTIVE AND DESTRUCTIVE TESTING METHODS
(2018-05-10)
CFRP (Carbon Fiber Reinforced Polymer) laminates have been used as externally bonded reinforcements for retrofitting and structural strengthening of concrete structures. The adequacy of the CFRP bonding highly depends on ...
NONUPDATING METHODS FOR THE CHARACTERIZATION OF NONLINEAR STRESS-STRAIN AND DELAMINATION FRACTURE PROPERTIES OF FIBER REINFORCED COMPOSITES
(2018-12-07)
Efforts to develop strength and life prediction analysis tools for aircraft composite structures have shown a great need to understand the complexity and interaction of failure modes. Many failure models are highly sensitive ...
STUDYING EFFECTS OF ADHESIVE LAYER ON ELECTRICAL SIGNALS OF PIEZOELECTRIC TRANSDUCER BONDED WITH STRUCTURE
(2018-01-24)
Piezoelectric wafer active sensors (PWAS) are the most attractive transducers for guided-wave or ultrasound based structural health monitoring (SHM) because of their light weight and compact size. In order to excite guided ...
A Comparison of Discrete Damage Modeling Methods: the Effect of Stacking Sequence on Progressive Failure of the Skin Laminate in a Composite Pi-joint Subject to Pull-off Load
(2019-05-07)
Discrete damage modeling of composite failure mechanisms including delamination, matrix cracking, and their interactions was performed for the skin laminate in a composite pi-joint test specimen subject to a pull-off load. ...
IMPACT OF MATERIAL MODELS ON IMMERSION COOLED ELECTRONICS PACKAGES AND RELIABILITY ASSESSMENT FOR CHIP-PACKAGE INTERACTION
(2021-05-13)
The immersion cooling for IT equipment has been around for decades. From thermal energy management perspective, immersion cooling is better than traditional cooling technology. However, there is need for more work in open ...
FLEXURAL STRENGTHENING OF TWO-WAY SLABS USING CFRP EXTERNAL LAMINATES
(2021-05-07)
Deterioration of reinforced concrete structures with time is a common phenomenon, which often leads to reduction in the load carrying capacity. To meet the coding requirements, strengthening of these structures is of utmost ...
ASSESSMENT OF MATERIAL STATE IN COMPOSITES USING GLOBAL DIELECTRIC STATE VARIABLE
(2019-12-04)
Composites are heterogeneous in nature and a fundamental understanding of the material response to applied mechanical, thermal, electrical and other multi-physical fields is required to efficiently design and synthesize ...
ANALYSIS OF LAMINATED CURVED BEAM WITH AND WITHOUT DEFECTS AND IMPERFECTIONS
(University of Texas at Arlington, Libraries, 2019-08-27)
Several studies have focused on the modeling and response characterization of composite structural members, with particular emphasis on composite curved beams. The class of curved beam is explored to determine mechanical ...
ADVANCED METHODS OF NONDESTRUCTIVE INSPECTION OF COMPOSITE STRUCTURES BASED ON LIMITED ANGLE X-RAY COMPUTED TOMOGRAPHY
(2017-09-01)
This research aimed to study the potential for breaking through object size limitations of current X-ray computed tomography (CT) systems by implementing a limited angle scanning technique. CT stands out among other ...
