Current and future high-contrast imaging instruments require extreme Adaptive Optics (XAO) systems to reach contrasts necessary to directly image exoplanets. Telescope vibrations and the temporal error induced by the latency of the control loop limit

Direct imaging of exoplanets requires overcoming the enormous contrast between the exoplanet and its host star, to distinguish the reflected light from the exoplanet, from the diffracted light of the star. Direct optimization of contrast, using nonli

Fatigue hardening and softening in materials result in different lives in low cycle fatigue, depending on the test mode. The problem is discussed based on the cyclic stress-strain relation, and a suitable testing mode is suggested for the design of s

Fracture toughness relation of high strength materials in bi-axial loading is analysed in conjunction with the stress intensity factors, their corresponding Mohr's type of circle and the crack angles. The critical crack angle with respect to the prin

Brittle fracture of components containing a crack of arbitrary orientation and subjected to biaxial loading is analysed based on the Mode I and Mode II stress intensity factors and fracture toughness relation. The critical orientation of the crack an

Effect of thickness on fatigue crack growth (FCG) behavior has been investigated at varying stress ratio in a quaternary Al-Li alloy. The thickness has been observed to influence FCG behavior in two opposite ways, depending on stress ratio. The crack
