DEVELOPMENT OF DIGITAL SHEAROGRAPHY FOR COMPLEX DEFECTS INSPECTION
(2021-11-09)Digital shearography measures the first derivative of the object surface deformation, which has the advantages of high sensitivity, full field, non-contact, realtime and anti-disturbance. It is widely used in materials ... -
EXPERIMENTAL IMPLEMENTATION OF A NEW DURABILITY / ACCELERATED LIFE TESTING TIME REDUCTION METHOD
(2021-11-13)Fatigue can be defined as a cyclic degradation process resulting in a failure at lower stress levels than the ultimate load. Fatigue reliability is defined as the probability that a structure will perform its intended ... -
2-D MODELING OF MOISTURE AND HEAT DIFFUSION IN ADHESIVELY BONDED JOINTS
(2021-11-15)In this dissertation research, a novel two-dimensional model is proposed for adhesively-bonded Single Lap Joints (SLJ) under combined mechanical loads and moisture/heat diffusion. Governing partial differential equations ... -
SOLUTION METHODOLOGY FOR CONSTRAINED EIGENVALUE PROBLEMS AND ITS APPLICATIONS WITH EXPERIMENTAL VALIDATION IN STRUCTURAL CHARACTERISTICS IDENTIFICATION
(2021-11-15)A numerical reverse algorithm was developed in this dissertation to find some unknown parameters of an object. For example, if the natural frequency of an object is known, find the mass of the particle placed at a specific ... -
LOAD DISTRIBUTIONS IN BOLTED SINGLE LAP JOINTS UNDER NON-CENTRAL TENSILE SHEAR LOADING
(2021-11-16)This study uses a numerically calibrated beam theory-based model to investigate the bolt load distributions in a preloaded two-bolt single lap joint under non-central tensile shear loading. The linear spring-based modeling ... -
GENERATION OF INTERNAL COMBUSTION ENGINE MAPS AND SPARK TIMING PROFILES USING METAMODELS
(2022-03-14)With the growth of computing technologies, many leading automotive companies tend to use simulation tools to reduce the number of actual engine testing for evaluating the performance of Internal Combustion (IC) engines. ... -
Self-Crack Healing of Engineering Ceramics
(2022-03-21)The purpose in its simplicity is to heal the damage in a sample composed of ceramic particles through the heat treatment or through applying another source to heal the damage might be through using a laser source at room ... -
PROCESS OPTIMIZATION OF AUTOCLAVE BONDED LIGHT-WEIGHT MATERIAL JOINTS
(2022-04-01)This dissertation research fills a gap in the existing open literature regarding the significance of autoclave cure process variables and their interactions on the static strength of lightweight material single lap joints ... -
Molecular Dynamics Simulation Of The Effect Of Particle Hardness On Tribological Properties Of Nanofluids
(2022-07-20)The determination of physical properties of nanofluids is mature, but the knowledge of tribological properties of nanofluids is limited. In this paper, the effects of surface roughness, fluid thickness, nanoparticle hardness, ...
