Research 
 Rosakis is the author of more than 260 works on quasi-static and dynamic failure of metals, composites, interfaces and micro-electronic structures, with emphasis on the use of high speed visible and IR diagnostics and laser interferometry for the study of thermal fatigue, catastrophic failure and dynamic localization. His early work includes the study of dynamic, ductile failure of structural metals by using high speed photography, the real-time measurement of temperature fields at the vicinity of dynamically growing cracks and adiabatic shear bands and the development of a variety of optical and dynamic infrared diagnostic methods. He and his coworkers invented Coherent Gradient Sensing, CGS, interferometry, a method sensitive to gradients of optical path gradients which has been used in both fracture mechanics and thin film stress and reliability measurements at the wafer level. Other interests include dynamic fragmentation; shear dominated intersonic rupture of inhomogeneous materials and composites, rupture mechanics of crustal earthquakes, shielding of spacecraft from hypervelocity micrometeoroid impact threats, the reliability of thin films and wafer level optical metrology. Rosakis holds thirteen US patents on thin-film stress measurement and in situ wafer level metrology as well as on high speed infrared thermography. In the late eighties, Rosakis introduced the concept of "laboratory earthquakes" and since then his research interests have included on the mechanics of seismology, the physics of dynamic shear rupture and frictional sliding and on laboratory seismology. The goal of this body of work is to create, in a controlled and repeatable environment, surrogate laboratory earthquake scenarios mimicking various dynamic shear rupture process occurring in natural earthquake events. Such, highly instrumented, experiments are used to observe new physical phenomena and to also create benchmark comparisons with existing analysis and field observations. The experiments use high-speed photography, full-field photoelasticity, digital image correlation (DIC) and laser velocimetry as diagnostics. The fault systems are simulated using two photoelastic plates held together in frictional contact. The far field tectonic loading is simulated by pre-compression while the triggering of dynamic rupture (spontaneous nucleation) is achieved by suddenly dropping the normal stress in a small region along the interface. The frictional interface (fault) forms various angles with the compression axis to provide the shear driving force necessary for continued rupturing. Rosakis and his co-workers, investigate the characteristics of rupture, such as rupture speed, rupture mode, associated ground motion under various conditions such as tectonic load, interface complexity and roughness. Both homogeneous and bimaterial interfaces (abutted by various elastic and damaged media) are investigated. Rosakis and his coworkers have been credited with the experimental discovery of the "intersonic" or "supershear rupture" phenomenon. They also have investigated this new phenomenon in various engineering and geophysical settings involving shear dominated rupture in the presence of weak interfaces or faults. Their experimental discoveries of supershear rupture has refocused the attention of the geophysics community to the study of supershear earthquakes. Another recent research interest for Rosakis is hypervelocity impact. Hypervelocity impact is a rising concern in spacecraft missions where man-made debris in low Earth orbit (LEO) and meteoroids are capable of compromising or depleting the structural integrity of spacecraft. To address these concerns, the goal of current research is to experimentally investigate the underlying mechanisms responsible for deformation and damage evolution during hypervelocity impact utilizing Caltech/JPL's Small Particle Hypervelocity Impact Range (SPHIR) facility. By combining high speed photography, optical, spectroscopic and infrared techniques, including Coherent Gradient Sensing (CGS) interferometry, the dynamic perforation behavior involving crater morphology, debris and ejecta formation and solid/fluid/plasma transitions and interactions have been examined.
