johnson & cook strength modelDynamic yield strength of mild steel is estimated when impacted by the steel balls launched by two stage-light gas gun in the velocity region 1900-5200 m/s. The ball impact provides a radial momentum to the target material resulting in a crater which spreManjit ...
Flexural test: Interlaminar shear strength of the composite offers resistance to bending load. It is done when a part is under bending load. • Impact test: It reveals the ability of the material to absorb the energy during the high rate of loading. Capacity is 1–300 J. • Hardness ...
Tensile and Charpy Impact Properties of High-Strength Bainitic Steels Fabricated by Controlled Rolling Process This study is concerned with tensile and Charpy impact properties of high-strength bainitic steels fabricated by controlled rolling process. Six kinds of s... HK Sung,SS Yong,B Hwang,......
The AISI 1018 mild steel plates with thickness of 5 mm were friction stir welded by tungsten based alloy tool with tool rotational speed of 1000 r/min and welding speed of 50 mm/min. Tensile strength of stir zone is higher (8%) compared to that of the base metal. This may be due ...
Microstructure: The shape of carbide precipitates in steel has a great effect on impact toughness. A tempered martensitic structure has the best combination of strength and fracture toughness. Tensile properties of such structures of the same carbon content and the same hardness are alike,...

Strength and adhesion properties of acrylic polyol‐epoxy polyol resin protective coating on mild steel substrate Purpose - The purpose of this paper is to improve the strength and adhesion properties of modified acrylic polyol resin using epoxy polyol resin (DEGBA).De... SR Rau,B Vengadaesvaran...
At high incidence velocity however, the performance was found to be dependent on target strength and projectile shape. Zhou and Stronge [12] studied the ballistic resistance of monolithic, double layered and sandwiched steel plates impacted at 0°, 30° and 45° obliquity by flat and ...
