Book Synopsis Modelling Hot Deformation of Steels by : John G. Lenard
Download or read book Modelling Hot Deformation of Steels written by John G. Lenard and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Aided Engineering may be defined as an approach to solving tech nological problems in which most or all of the steps involved are automated through the use of computers, data bases and mathematical models. The success of this ap proach, considering hot forming, is tied very directly to an understanding of material behaviour when subjected to deformation at high temperatures. There is general agreement among engineers that not enough is known about that topic -and this gave the initial impetus for the project described in the present study. The authors secured a research grant from NATO (Special Research Grant #390/83) with a mandate to study the "State-of-the-Art of Controlled Rolling". What follows is the result of that study. There are five chapters in this Monograph. The first one, entitled "State-of-the Art of Controlled Rolling" discusses industrial and laboratory practices and research designed to aid in the development of microalloyed steels of superior quality. Follow ing this is the chapter "Methods of Determining Stress-Strain Curves at Elevated Temperatures". The central concern here is the material's resistance to deformation or in other words, its flow strength, the knowledge of which is absolutely essential for the efficient and economical utilization of the computers controlling the rolling process.

Book Synopsis Modeling Steel Deformation in the Semi-Solid State by : Marcin Hojny
Download or read book Modeling Steel Deformation in the Semi-Solid State written by Marcin Hojny and published by Springer. This book was released on 2017-09-07 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a unique approach to integrated high-temperature process modelling, intended to serve as a design aid for new metal processing technologies. The second edition has been substantially expanded to include new content such as: a new algorithm and test results of 3D stereoscopic visualization; new programming procedures for modelling; the validation of computer simulation using experimental results; a multiscale model of grain growth; a conceptual methodology developing “high-temperature” CCT (continuous cooling transformation) diagrams, and many more examples validating the numerical simulations. The models presented are applied in comprehensive tests in order to solve problems related to the high-temperature deformation of steel. The testing methods include both physical tests using specialist laboratory instruments, and advanced mathematical modelling: the Finite Element method (FE), Smoothed Particle Hydrodynamics method (SPH) and Mo nte Carlo method (MC).This approach, which integrates the fields of physical and computer-based simulations, forms the basis for the described concept of integrated high-temperature process modelling, presented in detail in this book.

Book Synopsis A Modeling and Experimental Study of Deformation and Hot Tearing in Steel by : Charles Andrew Monroe
Download or read book A Modeling and Experimental Study of Deformation and Hot Tearing in Steel written by Charles Andrew Monroe and published by ProQuest. This book was released on 2008 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-phase model is presented that predicts solid deformation and damage as well as melt pressure, feeding flow, and shrinkage porosity. A viscoplastic constitutive theory with damage is used to model the solid deformation. Damage is a scalar quantity based on ductile fracture theory which is calculated from the inelastic volume deformation. This associative model smoothly transitions from rate-dependent behaviour at high temperatures to rate-independent behaviour at lower temperatures. The damage created by mechanically induced voiding is proposed as a new hot tear criterion. Hot tears are believed to initiate from locations with significant damage. The liquid feeding and shrinkage porosity is coupled to the solid deformation which enables the final damage prediction to be more accurate than previous hot tear criteria. This model has been successfully implemented in a general-purpose casting simulation code. Novel steel casting experiments have been designed and performed which measure the deformation and force from solidification to shakeout. Under certain experimental conditions, hot tears form in the test castings and the deformation and force during hot tear formation is also measured. The measured and predicted deformations and forces show good agreement with the simulation results. Furthermore, the damage predictions show good correspondence with hot tear indications on radiographs of the test castings.

Book Synopsis Study on Hot Deformation Behavior of High Carbon Low Alloy Steel by Constitutive and ANN Modeling and Development of Processing Maps by : Deepak Kumar
Download or read book Study on Hot Deformation Behavior of High Carbon Low Alloy Steel by Constitutive and ANN Modeling and Development of Processing Maps written by Deepak Kumar and published by . This book was released on 2020 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hot deformation behavior of high carbon low alloy steel was investigated by isothermal compression tests on Gleeble 3800 thermomechanical simulator in the temperature range of 850Degree C-1,100Degree C and in the strain rate range of 0.01 s -1 to 10 s -1 . The Arrhenius-type constitutive equations model and the artificial neural network (ANN) model were developed to investigate and predict the flow behavior of steel. The result of constitutive modeling showed that the material constants can be represented as a sixth degree polynomial function. The average apparent activation energy for hot deformation decreased from 441 kJ/mol to 350 kJ/mol, and the stress exponent decreased from 5.6 to 4.01, indicating the deformation mechanism to be dislocation glide and climb. The accuracy and effectiveness of the two models were compared using correlation coefficient and mean absolute error. Results showed that the ANN model almost perfectly predicted the flow behavior in terms of flow stress. Mean absolute errors in the Arrhenius-type constitutive equations model and ANN model are 7.2 % and 2.1 %, respectively. This confirms the better predictability of the ANN model over the analytical constitutive equations-based model. Processing maps were constructed using the dynamic material model, modified dynamic material model, and strain rate sensitivity maps at true strains of 0.3 and 0.6, which were correlated with microstructure evolution. It was observed that the instability region shrinks with increasing strain, which can be attributed to the fact that, for longer deformation, the stress value becomes constant and hardening-softening cycles cease to exist. Metallographic investigations showed the variety of instabilities such as cracks, voids, pores, and adiabatic shear bands, confirming the unstable region predicted by the processing maps.
