Net section resistance of steel angles connected by one leg [PDF]
Archives of Civil Engineering, 2022 In civil engineering structures, steel angles are often used as tensioned elements, because of their ease of fabrication and assembly. For practical reasons, angles are usually connected only by one leg, using a single row of bolts, and rupture of ...

Analysis of the Void Volume Fraction for S235JR Steel at Failure for Low Initial Stress Triaxiality
Archives of Civil Engineering, 2018 This paper deals with problems of failure mechanisms of S235JR structural steel. One of the fundamental parameters of the Gurson-Tvergaard-Needleman damage mechanics-based material model is considered in order to describe the behaviour of the material at

Ductile failure analysis of high strength steel in hot forming based on micromechanical damage model
MATEC Web of Conferences, 2016 The damage evolution of high strength steel at elevated temperature is investigated by using the Gurson-Tvergaard-Needleman (GTN) model. A hybrid method integrated thermal tensile test and numerical technique is employed to identify the damage parameters.
