Enhancement of mechanical properties of low carbon steel based on heat treatment and thermo-mechanical processing routes
Thermal treatments and thermo-mechanical processing routes were applied on a conventional structural steel (st37 steel: 0.12C-1.11Mn-0.16Si) for improvement of tensile properties and enhancement of work-hardening behavior. Full annealing resulted in a sheet with coarse ferrite grains and pearlite colonies arranged alternatively in distinct bands, which showed high ductility, low strength, and t...
متن کاملThermo Mechanical Analysis of Polypropylene/Calcium Carbonate Nano Composite using Thermo Mechanical Analyzer
Polypropylene is extensively used for varied applications due to its low cost, low density, high thermal stability and resistance to corrosion. Enhanced mechanical properties of Polypropylene can be achieved by mixing it with clays to form nanocomposites which increases its utility. Polypropylene Nano composites are formed by mixing polypropylene with calcium carbonate nano particles. This resu...
متن کاملThermo-hydro-mechanical Coupling in Clay Barriers
A complete thermo-hydro-mechanical model is presented to tackle the complex coupling problems encountered in clay barriers. A detailed formulation coupling the heat, moisture (liquid water and water vapour) and, air transfer in a deformable unsaturated soil is given. The formulation of the AlonsoGens’s mechanical model for unsaturated soil is also incorporated. The sensitivity to some parameter...
متن کاملThermo-mechanical behaviour of energy piles
Energy piles are an effective and economic means of using geothermal energy resources for heating and cooling buildings, contributing to legislative requirements for renewable energy in new construction. While such piles have been used for around 25 years with no apparent detrimental effect, there is limited understanding of their thermo-mechanical behaviour. This paper synthesises the results ...
متن کاملModeling Thermo-electro-mechanical Beams in Sugar
INTRODUCTION Qconv SUGAR is a simulation package for 3D MEMS devices that utilizes nodal analysis techniques [1]. It has been shown that nodal analysis is significantly faster than other simulation techniques and can be just as accurate. The latest version of SUGAR (v2.0) includes various models for 2D and 3D beams, electrical beams, and gap closing actuators [2]. In addition, SUGAR is easily e...
