The creep and creep rupture of SMC-R50 under different thermomechanical conditions
The creep and creep recovery behavior of a random fiber composite (SMC-R50) at elevated temperature and constant humidity were investigated experimentally and theoretically. The short time creep response for four constant stress levels at each of four selected temperature levels was experimentally …

A viscous-viscoelastic creep model
The creep data of 304 stainless steel at 1100 °F (593 °C) for pure tension, pure torsion, and combined tension and torsion under varying stress history were analyzed. The variable stresses are step changes in stress including complete unloading, reloading, step-up, step-down, and side steps in …

Creep predictions for turbomachinery components
Several theories of creep and creep rupture are reviewed. Specific attention is devoted to the brittle damage theory proposed by Kachanov. Creep, damage and life predictions for rectangular or circular cross section beams under bending and tensile loads are presented. Comparison with data for a Ni …

Continuum Damage Mechanics (CDM) modelling of dislocation creep in 9-12% Cr creep resistant steels
… material properties specifically that of creep degradation and deformation. This has been partially due to the reliance of creep life predictions in the past being based on accelerated creep testing and empirically based modelling. With the relatively recent revelations of empirically …

The effect of the interphase/interface region on creep and creep rupture of thermoplastic composites
… region on the static mechanical properties, creep and creep rupture behavior of thermoplastic (J2) composites was investigated. The mechanical properties of the J2 composites were altered by systematic changes in fiber surface chemistry. Four fiber systems were used including the AU4, AS4(1) …

Creep properties of source rocks using indentation : the role of organic matter on texture and creep rates
… of organic matter affecting texture and driving creep behavior in source rocks. To isolate the porous organic-rich clay composites, we adopt elaborate methodology that uses the mechanical properties probed with the indentation technique, chemistry obtained from spectroscopy, and chemo-mechanical …

Torsional creep of tin at high temperatures
Steady-state creep data are presented for tin tested in torsion at temperatures from 1000C to 228°C. Results obtained below 210°C verify observations of other investigators. A creep activation energy of 22.5 Kcal/mol in this temperature range is determined. Above 210°C, an abnormal increase in the …

Multiaxial creep models for 304 stainless steel
… equations were developed to describe creep strain of 304 stainless steel at 593 [degrees] C (1100 [degrees] F) under variable stresses of pure tension, pure torsion and combined tension and torsion. One was based on isotropic strain hardening concept and the other employed a state …
