    Abstract: This article studied the stress concentration in homogenous material using an optical method of caustics. The study on stress concentration is of great research value to evaluate the damage inside materials. In this work, one optical experimental method, caustics method, is introduced to study the mechanical behavior of an elastic plate of transpar... Show More

    Abstract: The present investigation was carried out to study the effect of machine pricked aonla and changes in chemical composition of aonla candy during storage when packed in sealed polyethylene bags (200 guage) up to 180 days at ambient (25°C) and refrigerated temperature (7°C). The respective values of moisture content, TSS, acidity, reducing sugars, no... Show More

    Abstract: In this paper the simulation results of hypersonic accelerator with pulse dynamic biasing system (PDBS) which provide external magnetic field compensation are given. The nearest analog of PDBS shown is Halbach-Array. Using magnetic compensation provides is shown to increase the magnetic field in inter-rail gap of the railgun up to 270% and to incre... Show More
