Particle Acceleration And Emission Processes In Mrk 421
, 2013 We investigate the X-ray and $\gamma$-ray flares of Mrk 421 on 2008 June 6-15 using the synchrotron self- Compton(SSC) model with electron acceleration, in which an evident correlation between the X-ray and $\gamma$-ray bands appears, while no ...

Correlations Between Metallurgical Characterization Studies, Exploratory Mechanical Tests, and Continuum Mechanics Approaches to Constitutive Equations [PDF]
, 1983 Austenitic stainless steels, such as types 316 and 304, are widely used as pressure vessel materials in the temperature range of 425 to 650 C. Stainless steel specimens were tested to rupture at two different stress levels sigma and sigma 2 sigma 1 sigma

Nonlinear Creep Constitutive Model of Rock Considering Hardening Effect
GeofluidsThe creep of rock is a complex mechanical phenomenon driven by internal stress adjustment and the interplay between hardening and damage effects. To precisely capture the nonlinearity of rock creep and the law of accelerated deformation, a hardening ...

A thermoviscoplastic model with damage for simultaneous hot/cold forging analysis [PDF]
, 2013 A constitutive model is presented for simultaneous hot/cold forming processes of steels. The phenomenological material theory is based on an enhanced rheological model and accounts temperature dependently for nonlinear hardening, thermally activated ...

Anisotropic yield functions in a co-rotating reference frame [PDF]
, 2000 In metal forming simulations large deformations are often treated based on objective formulations. Large rotations are accounted for by rotating the stress tensor or approximating the rotation by some integration rule for the rate of rotation.
