Elastic statics mainly relates to the connection between force and transmogrification, elastic body's invalidation, the guide line of design in invalidation.
Find failure root cause by performing component eletrical and physical failure analysis, such like curve tracing, SAM, decapsulation, cross section, SEM etc.
4 In multicoat systems adhesion failure may occur betweennbspnbspcoats so that the adhesion of the coating system to thenbspnbspsubstrate is not determined.
Distorsion,corrosion,erosion and abrasion mechanisms,concerning the faulty section,of the boiler s secondary superheater were studied by on-site measurements and by samples,cut from the tubes.
The failure of directly buried heat-supply pipeline is discussed, and the design essentials are put forward in accordance with local buckling and ovalization deformation.
In this paper, the possible reasons for Cd-Ni secondary battery to be out of work were discussed,and the nonserviceable Cd-Ni secondary batteries were successfully restored.
Analysis on leakage reasons of chlorine liquefier were anlysed from manufacture, test and application. The liquefier was failure, and the protective measures were put forward.
Research on the failure reasons of the cooling tube were carried out by means of macroexamination, thickness measurement, X ray diffraction, optical microscopy and chemical analysis.
In order to prevent failure of packer and provide theoretical basis for selection of unsetting shear pin, the unsetting force of packer must he calculated in design.
The results show that the failure is mainly attributed to the inappropriate heat-treatment technology of the locking nut and the hydrogen brittlement from electroplating of the stopping pad.
This heating helps to break down weak spots in the dielectric that otherwise might pass through the electrode undetected, only to fail during a later spark or hipot test.
