The elastoplastic deformation behaviors of hollow glass microspheres/iron syntactic foam under tension were modeled using a representative volume element (RVE) approach. The three-dimensional microstructures of the iron syntactic foam with 5 wt % glass microspheres were reconstructed using the random sequential adsorption algorithm. The constitutive behavior of the elastoplasticity in the iron ...

The Fe-Cr-Ni stainless steels are well known for their ductile behaviour at cryogenic temperatures. This implies development and evolution of plastic strain fields in the stainless steel components subjected to thermo-mechanical loads at low temperatures. The evolution of plastic strain fields is usually associated with two phenomena: ductile damage and strain induced martensitic transformation...

OBJECTIVES A training intervention comparing resistance exercise with or without whole-body vibration (WBV) was conducted to compare acute and chronic effects on functional and molecular parameters. METHODS A six-week training intervention was performed including 26 healthy males (26 years, SD=4). Two groups were analyzed in a parallel design performing either resistive exercise (RE, n=13) or...

The development of new type hydrogels featuring enhanced properties is a recent topic and particular interest for wide range industrial applications, especially in biomedical sector. present contribution focuses on the mutliscale modeling that are treated by enzymatic mineralization thus enriched with calcium phosphate. More specifically, phosphate forms spherical or honeycomb structures hydrog...

The need for quick and easy deflection calculations of various prefabricated slabs causes simplified procedures numerical tools to be used more often. Modelling full 3D finite element (FE) geometry such plates is not only uneconomical but often requires the use complex software advanced knowledge. Therefore, homogenization an excellent tool, which can easily employed simplify a model, especiall...

In this paper we develop a finite deformation micromechanical framework for modeling rate-dependent failure in unidirectional composites under off-axis loading. The model performance is compared with original experiments on thermoplastic carbon/PEEK tested at different strain-rates and angles. To achieve quantitative agreement the experiments, microcrack initiation criterion based local stress ...

Predicting the nonlinear mechanical response of short fiber reinforced composites (SFRCs) is a crucial and challenging task. In this paper, computationally efficient multi-scale strategy proposed to predict anisotropic elasto-plastic behavior SFRCs using intrinsic pure polymer fibers without requirements for reverse engineering. doing so, different simple unit cells are first examined find one ...

This paper presents two algorithms for generating compact test sets for combinational and full scan circuits under the transition and CMOS stuck-open fault models; Redundant Vector Elimination (RVE) and Essential Fault Reduction (EFR). These algorithms together with the dynamic compaction algorithm are incorporated into an advanced ATPG system for combin-ational circuits, called MinTest. The te...
