Thermomechanical Modelling and Simulation of C38 Thixoextrusion Steel

Thermomechanical Damage Modeling of F114 Carbon Steel

Abstract—The numerical simulation based on the Finite Element Method (FEM) is widely used in academic institutes and in the industry. It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as fracture. But, the results of such numerical model depend strongly on the parameters of the constitutive behavior model. The influences of thermal and m...

Metallurgical Modelling of Thermomechanical Processing

Advance Modelling and Simulation of Industrial Boilers

This paper presents some of the results of the simulation in the radiation section of an industrial boiler using an advanced mathematical model. Calculations are described for the flow, heat transfer, and chemical reaction processes occurring within a gas-fired cylindrical furnace. The calculation procedure is a two dimensional one in which the main hydrodynamic variables are the velocity and s...

Effect of Thermomechanical Processing on the Microstructure and Mechanical Properties of a Duplex Stainless Steel

Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...

Behavioral Modeling and Simulation of MEMS Electrostatic and Thermomechanical Effects

This thesis extends and updates the N__qodal Design of Actuators and Sensors (NODAS) library previously developed at Carnegie Mellon University. NODAS is a library of atomic element lumped parameter behavioral models written in Verilog-A, an analog hardware description language (AHDL). It is used for the simulation of MEMS devices in a SPICE-like circuit simulator. Physics modeling, accuracy ve...
