The Spot welding is widely used for joining thin sheets in different industries; such as automotive industry. This method of welding is very easy to automate and maintain. In this study, the effect of nugget diameter on the tensile-shear strength of the spot welding joints was investigated. The specimens were manufactured from AISI 1008 HR sheets with 1.0 mm thickness. The eight different elect...

In the present study we have attempted to verify a theoretical model of grab versus strip strengths of fabrics [Textile Research Journal, 2003, 73(2), 165–171] through experimental investigation. Five different fabrics were included in this study, and three related parameters were investigated including the modulus ratio of the specimen (shear versus tensile moduli), the specimen gauge length a...

Understanding the complicated failure mechanisms of hierarchical composites such as fiber yarns is essential for advanced materials design. In this study, we developed a new Monte Carlo model for predicting the mechanical properties of fiber yarns that includes statistical variation in fiber strength. Furthermore, a statistical shear load transfer law based on the shear lag analysis was derived...

Strength reduction finite element method (SRFEM) has been widely used to analyze the slope stability. Strength Reduction Factor (SRF) is yielded as the slope Factor Of Safety (FOS) when a running-though shear failure zone comes into being, in which the Plastic Element EQuivalent strain (PEEQ) is employed as the judgment of shear failure initiation in this paper. Moreover, the filed variable is ...

We explore BiFeO3 under tensile strain using first-principles calculations. We find that the actual structures are more complex than what had been previously thought, and that there is a strong shear deformation type structural instability which modifies the properties. Specifically, we find that normal tensile strain leads to structural instabilities with a large induced shear deformation in (...

Lignin, a byproduct of paper and pulp industries, is a sustainable, inexpensive biomaterial with potential as composite filler. Past research on polyolefin/lignin composites made by melt processing has led to modest increases in Young’s modulus and drastic reductions in tensile strength and elongation at break relative to neat polymer. Here, green hybrids of low density polyethylene (LDPE) and ...
