The paper presents a new fatigue damage assessment model defined for the strain energy density parameter. is calculations in frequency domain case of narrowband loading. Analytical expressions are derived probability function peaks, level crossing spectrum, and expected that directly linked to power spectral theoretical proof which shows obtained equal stress model. A numerical example used ver...

abstract- bruising degrades the quality of fresh apple fruits. reducing bruise damage is of utmost importance in designing and developing processing equipments. the main objective of the present study was to introduce an analytical method to predict the allowable static load applicable to apple fruits. to predict the strain energy absorbed by the fruit, a point load was applied on the solid sph...

Abstract To study the dynamic damage and fracture of metamorphic limestone under explosive load stability surrounding rock, stress-strain curve, morphology, energy dissipation characteristics in Dahongshan mining area different strain rates were studied by Hopkinson pressure bar (SHPB), stress wave analysis, fractal theory. The experimental results show that crushing form degree are significant...

Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...

In an earlier paper it was suggested that a knowledge of the elastic-stress variation in the neighborhood of an angular corner of an infinite plate would perhaps be of value in analyzing the stress distribution at the base of a V-notch. As a part of a more general study, the specific case of a zero-angle notch, or crack, was carried out to supplement results obtained by other investigators. Thi...

The process of adaptive bone remodeling can be described mathematically and simulated in a computer model, integrated with the finite element method. In the model discussed here, cortical and trabecular bone are described as continuous materials with variable density. The remodeling rule applied to simulate the remodeling process in each element individually is, in fact, an objective function f...
