This paper discusses recent theoretical developments on fracture at elevated temperature in the presence of overall plastic (dislocation) creep. Two topics are considered: 1. Stress fields at tips of macroscopic cracks in creeping solids: Here consideration is given to the transient development of an effectively steady state of creep in a cracked body, following sudden load application for whic...

Creep damage is one of the serious problems for the high temperature industries and computational approach (such as continuum damage mechanics) has been developed and used, complementary to the experimental approach, to assist safe operation. However, there are no ready creep damage constitutive equations to be used for predicting the lifetime for this type of alloy, particularly for low stress...

the purpose of this study was twofold: (a) to assess the retention of two word types (synonyms and homonyms) in the short term memory, and (b) to investigate the effect of these word types on word learning by asking learners to learn their persian meanings. a total of 73 iranian language learners studying english translation participated in the study. for the first purpose, 36 freshmen from an ...

objective: for decades, exercise has been considered as a cornerstone for managing diabetes. the current study aimed to determine the effects of short-term exercise on blood glucose, lipids and hba1c in type-2 diabetes mellitus. materials and methods: a total of 61 diabetic patients were randomly selected. later, subjects with capability of doing exercise took part in a special four-week exerci...

Retinal action potentials were recorded at the corneas of light-adapted wolf spider eyes in response to large positive and negative step changes in background illumination. These incremental responses were superimposed upon the steady-state DC responses to the background illumination. Both positive and negative step responses had peaks which overshot the DC levels to which they decayed. The ove...

background: patellar mal tracking is responsible for pain and disability in patellofemoral pain syndrome (pfps). patellar kinesio taping may have different effects on short and long term usage. the aim of this study is to compare the effect of short term and long term patellar kinesio taping in patellar position on women with patellofemoral pain syndrome using magnetic resonance imaging (mri). ...

Original scientific paper The nonlinear creep characteristics of typical clays in the coastal area of Tianjin were studied by consolidated-undrained triaxial creep tests. The tests were performed via the stepwise loading method, and the creep curves of the soft clays under different stress states were obtained from the raw data processed by Chen and Kang’s method. The experiments showed that th...

Fibre reinforced concretes (FRCs) are composite materials now largely adopted in structural applications given their mechanical properties terms of the residual tensile strength, almost absent for plain concrete. The short-term behaviour these material has been deeply studied, while time-dependent deformations have received less attention from scientific community. present paper presents experi...
