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...

Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...

The progressive collapse behavior and energy release of columnar jointed basalts (CJBs) can be greatly influenced by different joint distance ratios. By adopting the digital image correlation, a series heterogeneous CJB models are established. continuous fracture process acoustic emissions (AEs) captured numerically under varying lateral pressures. load curves ratios model boundaries analyzed. ...

Nonlinear matrices employed in asphalt-based composites exhibit a prominent nonlinear elastic-viscoplastic-viscodamageable mechanical response. The constitutive model for this type of requires significant experimental effort to identify the material constants. To alleviate characterization without losing reliability prediction, paper presents fast procedure decoupling elasto-viscoplastic respon...

Many researchers have proposed imaging the stiffness distribution in breast tissue to enhance diagnosis of disease. They suppose that cancers are much stiffer than the surrounding tissue but to our knowledge no measurements have been made of these properties that accurately characterize them over a wide range of strain. We hypothesize that there is a correlation between elastic modulus in compr...

In order to further investigate the strain rate effects on characteristic stresses and acoustic emission parameters of rock under quasi-static compression, uniaxial compressive tests were conducted cylindrical specimens measuring 50 mm in diameter 100 height using a material testing machine multi-channel monitoring system at rates ranging from 10 –6 s −1 –2 . The stress-strain curves samples, s...

in this paper the response of cantilevered reinforced concrete (rc) beams with smart rebars under static lateral loading has been numerically studied, using finite element method. the material used in this study is superelasticshape memory alloys (se smas) which contains nickel and titanium elements. the se sma is a unique alloy that has the ability to undergo large deformations and return to t...

Abstract BaTiO 3 single crystals were deformed in compression along the $$\langle 110\rangle$$ ⟨ 110 ⟩ crystal axis to study plastic deformability and dislocation structures at high temperatures under different loading conditions. The yield strength is ...

The following proceeding presents a multiscale approach to investigate the hydraulic anisotropy and retention behavior in porous materials involving deformation effects. Concerning former, single-phasic fluid flow simulations using lattice Boltzmann method (LBM) are initially accomplished at pore-level geometry of Bentheimer sandstones provided by X-ray microscopy several degrees compression co...
