The thermomechanical buckling of simply supported thin shallow spherical shells made of functionally graded material is presented in this paper. A metal-ceramic functionally graded shell with a power law distribution for volume fraction is considered, where its properties vary gradually through the shell thickness direction from pure metal on the inner surface to pure ceramic on the outer surfa...

in this study, the effects cold rolling and annealing parameters during thermomechanical processing of the aisi 201ln stainless steel were investigated. the cast samples were homogenized, hot-rolled and solution-annealed to acquire a suitable microstructure for the subsequent thermomechanical treatment. unidirectional and transverse multi-pass cold rolling at 25, 0 and -15 °c was carried out to...

The mechanical properties and microstructural developments of 321 stainless steel during thermomechanical process were investigated. The repetitive cold rolling and subsequent annealing were conducted to achieve nanocrystalline structure in an AISI 321 stainless steel. Heavily cold rolling at −20°C was conducted to form martensite in metastable austenitic steel. The process was followed by anne...

interstial free steels have good formability and also excellent deep drawability. these features make them one of the applicable materials in automotive industry. chemical composition and thermomechanical treatment used to process these steels have important role in final properties of them. in this study, the effect of chemical compositon on texture, anisotropical properties and bake hardenabi...

Silicon carbide fibres have proven to be an excellent reinforcement material in ceramics and other composites due to their high strength and stiffness and good thermomechanical stability. The thermal diffusivity/conductivity of SiC based fibres has been reported earlier [1]. The methods used so far for the fibres have been mainly indirect and based on using a composite of known composition and ...

We investigate the influence of interfacial treatment on the matrix-filler interaction using a meltmixing process to fabricate robust and highly stretchable dielectrics. Silicone oil and silane coupling agent are studied as possible solutions to enhance the compatibility between the inorganic fillers and polymer matrix. Morphology, thermomechanical and dielectric behavior of the prepared specim...

In this paper, the effect of thermomechanical loading on the behavior of deflection-based harvested energies from a shape memory polymer system is experimentally investigated. Samples are created with honeycomb cells from poly-lactic acid using additive manufacturing techniques. The shape memory effect in shape recovery and force recovery paths are studied under thermomechanical tests in bendin...
