A previous constitutive modeling for single-phase steels is extended using the mixing law to predict behavior of hot deformation in dual phase ferritic-austenitic intercritical zone Fe-C-Mn-Si alloys. Mixing considers two phases instead one, so one formula was modified. The constant’s values used represents average same conditions austenitic and ferritic model. amount each determined as functio...

In this paper, a discontinuity in beams whose intensity is adjusted by the spring stiffness factor is modeled using a torsional spring. Adapting two analyses in strong and weak forms for discontinuous beams, the improved governing differential equations and the modified stiffness matrix are derived respectively. In the strong form, two different solution methods have been presented to make an a...

In this research, the exponential stretched based hyperelastic strain energy was modified to provide the unstressed initial configuration. To this end, as the first step, the model was calibrated by the experimental data to find the best material parameters. The fitting results indicated material stability in large deformations and basic loading modes. In the second step, the initial pseudo str...

The influence of risk perception and risk attitudes in the process of accepting genetically modified (GM) food is often ignored, and particularly whether both constructs (latent variables) have a combined effect in explaining consumer acceptance. Similarly, the inclusion of organic product standards juxtaposed to GM food is unknown. This paper attempts to shed some light on this question by exa...

From the pavement construction emission perspective, bitumen emulsion is considered more environment-friendly than conventional because of its much lower temperature. However, faces major concern low mechanical strength especially at high service temperatures. To improve performance emulsion, waterborne epoxy resin can be used as a modifier. Nevertheless, there still lacks fundamental understan...
