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...

the present study assesses the seismic performance of steel moment resisting frames (smfs) retrofitted with different bracing systems. two structural configurations were utilized: ordinary concentrically braces (ocbfs), buckling-restrained braces (brbfs). a 7-story and 18-story steel perimeter smfs were designed with insufficient lateral stiffness to satisfy code drift limitations in high seism...

We study the thermoelectric transport under shear strain in two spatial dimensional quantum matter using holographic duality. General analytic formulae for DC conductivities subjected to finite are obtained terms of black hole horizon data. Off-diagonal conductivity matrix appear also at zero magnetic field, resembling an emergent electronic nematicity which cannot nevertheless be identified wi...

When different strain hardening, strain-rate sensitive and temperature softening materials are used for scaled model prototype, the traditional similarity laws of solid mechanics will be broken. Although research works in last twenty years have developed correction methods initial conditions to compensate distortion, their basic factors practically impeded inherent non-direct (depending on unkn...

Centrifuge modeling has been considered as an effective means of studying flexural soil–pile interaction, yet the conventional use elastic material to model RC pile prototype is unable reproduce important nonlinear quasi-brittle behavior. It also remains a challenge numerically interaction due nonlinearity both soil and materials. This paper presents small-scale for testing soil–structure under...

It has been reported for a long time that methane hydrate presents strain hardening, whereas the strength of normal ice weakens with increasing strain after an ultimate strength. However, the microscopic origin of these differences is not known. Here, we investigated the mechanical characteristics of methane hydrate and normal ice by compressive deformation test using molecular dynamics simulat...

We report on the low-cycle fatigue behavior of single-phase, face-centered cubic CoCrNi and CoCrFeMnNi at room temperature. Both alloys manifest cyclic hardening followed by softening a near steady state until failure. exhibits higher strength, lower inelastic-strain, longer lifetime than CoCrFeMnNi. For both alloys, microstructural investigations reveal no noticeable changes texture, grain siz...

Abstract We investigate the effects of salt concentration on rheological properties dipeptide hydrogel fibres at liquid-liquid interfaces. The interfaces were subjected to large amplitude oscillatory dilation (LAOD) experiments across a range oscillation strains and frequencies. Lissajous plots pressure-strain used for characterizing viscoelastic identifying apparent yielding. show that key asp...

Welding of steel is a technique frequently used in practical engineering applications; however, their mechanical performance strongly dependent on the physical metallurgical status weldments. In present study, fully reversed, strain-controlled low-cycle fatigue (LCF) tests were conducted 10CrNi3MoV and its undermatched weldments with strain amplitudes varying from Δ ε = ±0.5 to ±1.2%. Both base...

advanced high strength steels (ahss) have recently attracted great attention because of their superior mechanical properties. a modern group of these steels, known as twinning induced plasticity (twip) steels, shows a unique combination of strength and ductility even at high rates of strain. in order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...
