TL;DR: In this article, the effects of various line heat input energy on the mechanical properties of S690-QT steel welded sections through a series of carefully planned and executed standard tensile tests were investigated.

TL;DR: In this paper, the authors developed full range true stress-strain curves of various steel materials for large deformations, which are then incorporated into advanced finite element models to simulate large deformation fields of these steel coupons observed in the tensile tests.

TL;DR: In this paper, a detailed experimental investigation into structural behavior of S690 steel materials under both monotonic and cyclic loading conditions is described, and a detailed account of the test results is provided.

TL;DR: In this paper, a series of pilot tests on a total of 18 coupons of S690 steel plates, welded joints and weld metals with different heat input energy during welding have been conducted to examine their deformation characteristics under tension.

TL;DR: In this article, an integrated experimental, theoretical and numerical investigation to formulate a full range constitutive model for high strength S690 steel member at large deformations is reported, and the proposed instantaneous area method has been developed and calibrated against test results of a total of 30 standard tensile tests on S690 cylindrical coupons, and formulated with key mechanical properties of engineering stress-strain curves readily obtained from these tests.
