The Ballistic Behavior of High Strength, Low Alloy-100 Steel at Sub-zero Temperatures
The ballistic response of the high strength, low alloy (HSLA-100) steel at ambient and temperatures of -400°C, -800°C and -1960°C is investigated in this work. Lambert-jonas equation is used to fit the experimental results into a curve. The effect of quenching on ballistic behavior of HSLA-100 is also studied. The experiments are conducted on 3mm thick rectangular specimens impacted by blunt ti...
متن کاملBehavior of high strength structural steel at elevated temperatures
This paper presents the mechanical properties of high strength structural steel and mild structural steel at elevated temperatures. Mechanical properties of structural steel at elevated temperatures are important for fire resistant design of steel structures. However, current design standards for fire resistance of steel structures are mainly based on the investigation of hot-rolled carbon stee...
متن کاملA Model for Concrete at High Temperatures
Prediction of concrete performance at high temperatures is of great importance, in particular for safety evaluation of concrete structures in fires in tunnels and high buildings or in thermal hazard situations like hypothetical core disruptive nuclear accidents. High temperatures induce strong physical and chemical changes in the micro-structure of concrete that affect its mechanical behaviour....
متن کاملThermo-elasto-viscoplastic Analysis of Problems in Extension and Shear
The problems of extension and shear behavior of structural elements made of carbon steel and subjected to large thermomechanical loads are investigated. The analysis is based on nonlinear geometric and constitutive relations, and is expressed in a rate form. The materiai constitutive eqtiations arc capab!e of reproducing all nonisothermal, elasto-viscoplastic characteristics. The results of the...
متن کاملPrediction and control of subsurface hooks in continuous cast ultra-low-carbon steel slabs
Subsurface hook formation during initial solidification in the continuous casting mould degrades the quality of steel slabs owing to the associated entrapment of argon bubbles and non-metallic inclusions. To minimise hook depth and to improve slab quality, extensive plant experiments were performed and analysed to quantify the effect of casting parameters on hook characteristics using the no. 2...
