the dissipated energy from periodic deformation is regarded as the main reason for heat generation and temperature rise inside the tire domain. however, the mechanical behavior of rubber parts is highly temperature dependent. in most performed investigations, the influence of thermal effects on stress/ deformation fields of pneumatic tires is ignored and just temperature distribution is conside...

the new non-conventional cutting process by the use of thermal shock is a convenient procedure for cutting the brittle materials such as glasses and ceramics. this method is based on the application of localized thermal shock to brittle materials by the use of hot air jet, which induces thermal stresses at the tip of an existed pre-crack. due to the thermo-elastic behavior of materials, the pre...

the effects of physical, thermal and mechanical parameters on curing microthermal residual stresses are studied, based on the energy method, to present a theoretical solution for prediction of residual stress felds. a fnite element analysis is developed to compare the theoretical and numerical results together. there is found to be a good agreement between the results of the two methods. howeve...

Climate change, exerting thermal stress, and habitat destruction and fragmentation, resulting in genetic drift and inbreeding, are amongst the most disturbing human activities that endanger global biodiversity. We studied the interplay between these 2 processes using Drosophila melanogaster as a model organism and investigated how inbreeding affects the response to thermal stress. We found that...

We report calculated elastic tensors, axial Grüneisen parameters, and thermal stress distributions in Al2Mo3O12, ZrMgMo3O12, Sc2Mo3O12, and Y2Mo3O12, a series of isomorphic materials for which the coefficients of thermal expansion range from low-positive to negative. Thermal stress in polycrystalline materials arises from interactions between thermal expansion and mechanical properties, and bot...

Heat stress and reduced feed intake negatively affect intestinal integrity and barrier function. Our objective was to compare ileum protein profiles of pigs subjected to 12 hours of HS, thermal neutral ad libitum feed intake, or pair-fed to heat stress feed intake under thermal neutral conditions (pair-fed thermal neutral). 2D-Differential In Gel Electrophoresis and gene expression were perform...

in this study, effect early age feed restriction and thermal conditioning on growth ,carcass characteristics broiler chickens subjected to heat stress was evaluated. three hundred chicks (cobb500) were randomly divided into four equal groups as treatments including thermal conditioning group (tc), feed restriction-thermal conditioning group (tcfr), feed restriction group (fr) and control group ...

Six Holstein cows (averaging 475 kg body weight, 2.3 parities and 96 d in lactation) fitted with catheters in the hepatic portal vein, mesenteric vein and intercostalis posterior artery were exposed to treatments of thermal comfort environments with libitum or restricted (75% of ad libitum) DM intake and a thermal stress environment with ad libitum intake in two balanced 3 x 3 latin squares to ...
