The aim of the study is to investigate the evolution of internal stresses and non-homogeneous plastic deformation in quenching by numerical simulation. This paper presents the finite element model of quenching of axisymmetric components and the results of various numerical experiments. In the simulation, first the temperature distribution is determined as a function of geometry and time, Then. a model is described to give the volume fractions of phases as a function of time for the corresponding cooling curves. Next. thermo-elastic -plastic approach is applied to describe the stress-strain response during cooling, and to predict the residual stresses of the first order. The computer program was written in Fortran, and material properties were input as a function of the individual phases and temperature.

Simulation of Drop-Weight Impact Test on Composite Laminates using Finite Element Method
Bozkurt, Mirac Onur; Parnas, Levend; Çöker, Demirkan (Elsevier BV; 2019-01-01)
This study presents the simulation of standard drop-weight impact test on a [0/90/0]s composite laminate. For this purpose, a three-dimensional virtual test setup is developed in ABAQUS/Explicit finite element tool. Hemispherical impactor and specimen fixture are modeled as rigid bodies. Composite plate is modeled as a 3-D deformable solid and discretized using a biased mesh for computational efficiency. For simulation of ply damage in the composite laminate, a continuum damage mechanics based damage model ...
Numerical simulation of solidification kinetics in A356/SiCp composites for assessment of as-cast particle distribution
CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2009-06-01)
The present work is aimed at studying the effect of solidification rate on reinforcement clustering in particle reinforced metal matrix composites (PMMCs) through numerical simulations and experimental studies. A macrotransport-solidification kinetics (MTSK) model was used to simulate the solidification kinetics of the PMMCs. The experimental validation of the numerical model was achieved through the Newtonian and Fourier thermal analysis methods. Results reveal that the MTSK model can be successfully used ...
Numerical and experimental analysis of quench induced stresses and microstructures
Gür, Cemil Hakan (1998-01-01)
Numerical and experimental studies have been carried out to investigate the evolution of residual stresses and microstructures in quenched steel components. In the numerical analysis, a finite element model is implemented for predicting the temperature field, phase changes with their associated internal stresses in axisymmetrical components. The model is verified by several comparisons with other known numerical results. Case studies are performed to investigate the effects of the quench bath temperature an...
Technological characteristics of abrick masonry structure and their relationship with the structural behaviour /
Aktaş, Yasemin Didem; Türer, Ahmet; Department of Archaeometry (2006)
The aim of this study is to investigate the physical and mechanical properties of construction materials in relation with the structural behaviour of a historic structure. Within this framework, the brick masonry superstructure of Tahir ile Zuhre Mescidi, a XIIIth century Seljuk monument in Konya was selected as case study. The study started with the determination of the basic physical (bulk density, effective porosity, water absorption capacity), mechanical (modulus of elasticity, uniaxial compressive stre...
