TL;DR: In this article, the effects of high temperature treatment on the mechanical properties of Q235 steel have been studied, including the yield strength, ultimate strength, elastic modulus, elongation percentage and necking percentage.
Abstract: The mechanical properties of Q235 steel after high temperature treatment were discussed. The hot treating temperature is 200 ℃, 400 ℃, 600 ℃, and 800 ℃, respectively. The experimental specimens were cooled in two different cooling modes, which are natural cooling mode and swamp cooling mode. After cooled, the surface characteristics of the specimens including color changes and carbonized situation were described in the field. The two influence factors of the mechanical properties of Q235 steel including hot treating temperature and cooling mode were studied qualitatively, and the mechanical properties of Q235 steel were discussed in this paper including the yield strength, ultimate strength, elastic modulus, elongation percentage and necking percentage. Finally, the mathematical modes of yield strength and ultimate strength in two cooling modes were simulated by the least square method, and the modeling values were compared with the experimental values. The results show that the mechanical properties of Q235 steel in the mode of natural cooling are almost invariant, but the mechanical properties are closely related to the heat treating temperature in the mode of swamp cooling. Especially the mechanical properties of Q235 steel are changed obviously when the heat treating temperature of the specimens reaches 600 ℃.

Abstract: By the analysis of a simply supported reinforced concrete beam,the using method,skills and con- siderations of the damaged plasticity model for concrete were discussed at length.Using parametric analyses, effects of the dilatation angle,tension stiffening,tension damage factor etc on the result were studied.Some valuable advices were promoted for accurate nonlinear finite element analysis in reinforced concrete structures using this model.
TL;DR: This paper compared several methods to define the damage parameter in the concrete damage plasticity model and their working conditions by literature review and provides a recommendation on how to define this parameter in ABAQUS.
Abstract: The concrete damage plasticity model is acknowledged as an effective model to simulate the concrete inelastic behavior under cyclic loading in the ABAQUS. Therefore,it is a widely used multi-purpose FEM analysis software in civil engineering. The model is also widely used in elasto-plastic time-history analysis in high-rise building design. However,there is no reasonable way to define the damage parameter in the concrete damage plasticity model so far. This paper compared several methods to define the damage parameter and their working conditions by literature review. It provides a recommendation on how to define the damage parameter in ABAQUS.
