The cylinder made of 98W-Ni-Fe and 97W-Ni-Cu packed with TNT and RDX respectively can fragmentate into well-distributed fragments under explosive loading conditions,and the quality of the fragments are among 0.1-1g.
Based on uniaxial experimental data of a nickel-based superalloy Udimet 720Li under monotonic tension, symmetrically cyclic loading and creep loading, the paper studied to utilize the Bodner-Partom unified constitutive theory to model the mechanical behaviors of the material under these three different loading conditions for the first time.
Objective: To compare the biomechanical stability of the new sacral screw and the conventional sacral screw under different physiological activities and loading conditions, to provide the basis of biomechanics for the clinical application of the new type sacral internal fixation in future.
The multi-potential surface model in stress space is put forward, and the stress-strain behavior of an element under different loading conditions are simulated based on both the multi-potential surface model and Duncan-Chang’s E-μ model with the same parameters.
Applying this new model for predicting strength, we investigate different lamina properties, lay-up configurations and combined loading conditions’ effects on the strength and draw stress-strain behaviors and failure envelopes of composite laminates and comparative figures between the predicted values and experimental ones for somearrangements of the laminates.
(1) the loading conditions of a composite laminate: fiber direction along loading direction is good for improving the critical buckling load of a composite laminate under the other three aspects that is known.
According to the operation experience of the Schnabel car,the structure analysis model for the Schnabel on 380 t Schnabel car is set up,the boundary limiting conditions and loading conditions of the Schnabel are analysed comprehensively.
The technique of VIRTUAL PROVING GROUND takes the entire vehicle as research object, and takes Ls-Dyna as the tool to get the answer. It has consider in many kinds of nonlinear factors and the actual loading conditions. It can be used to realize the accurate simulation of vehicle collision, the safety of crew members, the fatigue life, NVH and so on.
By using Melnikov-Holmes method, we discussed the criterion of the chaotic vibration may occuring in an elastic rectangular thin plate which is simply supported along its all four edges- The approach considered here is applicable to extensive problems with various boundary and loading conditions.
We have studied basic parameters of emission processes as functions of the crack edge velocity, its dimensions and depth in the material with due account of its elastic and strength characteristics and loading conditions.
Effect of Loading Conditions on Informative Parameters and Signal Spectra of Acoustic Emission in Samples of Carbon Steels
The kinetics of damage accumulation in TiN coatings under various loading conditions has been investigated using spectral parameters of isolated acoustic emission pulses and their integral ow characteristics.
Under such loading conditions, the density of two-dimensional (2D) electrons at the heterointerface is determined primarily by a piezoelectric field induced in the  direction.
Under the same loading conditions, the rate of microplastic deformation of ultrafine-grained titanium is lower than that of coarse-grained titanium and the rate peaks shift toward high temperatures.
