Nevertheless, adhesive joint inevitably contains flaws or discontinuities at the interfaces. Moreover, even in the perfectly bonded adhesive joint, the existance of stress singularity due to the elastic mismatches which develops at the region of interface corner may initiate failure. As such, adhesive joints often fail unexpectedly and severely under a relatively low mechanical or thermal load in service.Therefore, in order to ensure high reliability and significant strength performance of adhesive joints, the strength and fracture toughness of adhesive joints should first be properly determined.In this dissertation, the strength and fracture toughness of epoxy adhesively bonded joints of dissimilar metallic adherends under a remote uniaxial tensile load were examined on various adhesive bond thicknesses and several scarf angles. ····· 10361147309

The elastic SNCF increases as the net-to-gross diameter ratio do /Do increases and reaches a maximum at do /Do 0.7. Beyond this value of do /Do it rapidly decreases to unity with do /Do. The elastic SNCF of the extremely deep notch of do /Do = 0.2 is almost equal to that of the shallow notch of do /Do=0.95. Nevertheless, the new SNCF of the shallow notch sharply increases with plastic deformation at the notch root, while the new SNCF of do /Do= 0.2 increases only slightly. The new SNCF of the deep notch of do /Do = 0.6 also increases with plastic deformation and reaches a peak value. This peak value is nearly equal to or slightly less than that of the shallow notch and hence the plastic SNCF of shallow notches cannot be neglected.

The structural health monitoring can be performed through vibration responses measured by sensors instrumented in the structure. Then changes in the dynamical behaviour of the system are identified through the development of identification and detection techniques. Damage or nonlinearity onset is considered responsible for the changes. The identification of damages and nonlinearity onset is always based on the comparison between a current and the reference (normal) states. The robustness of the methods is illustrated on a clamped beam structure with a geometrical nonlinearity at the end. Other examples are considered such as an aircraft mock-up with different levels of damage, some industrial applications and real-life structures. ····· 10361146646

Then the recipe is being prepared by spectrophotometer or manually and sent for the approval. After the approval of lab-dip, the recipe is sent to the dyeing floor for the bulk production. The difficulties found during the bulk dyeing process are that, the recipe of the dyeing lab does not give the same shade in the bulk dyeing. This creates lots of problem in the dyeing section. It is a very challenging job for a dyer to match the shade of the bulk production to the Lab-dip. But due to this problem lab to bulk reproducibility is being hampered. This is the main reason of dyeing reprocessing and refers several times for re-dyeing and stripping. Both of which are not economical practice for a dye house.

To consider such effect, modal analysis is required to be performed while in operation. A new method, namely Impact-Synchronous Modal Analysis (ISMA) utilising the modal extraction techniques commonly used in Experimental Modal Analysis (EMA) but performed in the presence of the ambient forces, is proposed. ISMA applies Impact-Synchronous Time Averaging (ISTA) technique which is effective in determination of dynamic characteristics of a rotor dynamic system while in rotating condition. Based on experimental modal data, the effectiveness in open crack detection on rotor shaft is established. Lastly, the concept of virtual instrumentation is introduced here to overcome the limitation imposed by the conventional FFT analyzers without going into the other extreme of software development. The software also enables complex and expensive hardware to be replaced.
