Abstract It is well known that the light-ray trajectories follow a curved path in gravitational field. This has been confirmed observationally where light rays coming from distant astronomical objects are seen to get bent Sun’s We explore here bending of electric field lines due gravity. determine, theoretical perspective, not only exact shapes rays, emitted isotropically by source supported fi...

The Welding in cold formed areas is not only an open question for statically loaded sections (brittle fracture) but also for dynamically loaded structures (fatigue resistance). A lot of structures are subjected to dynamic loadings and unfortunately very little information about the influence of welding in the cold formed areas on fatigue resistance is available. In order to establish the fatigu...

The demand for real-time or in situ structural health monitoring has stimulated efforts to integrate self and environmental sensing capabilities into structural composite materials. Essential to the application of smart composites is the issue of the mechanical coupling of the sensor to the host material. In this study various methods of embedding sensors within the host composite material are ...
