The composite group investigates endlessly the features of natural fiber/thermoplastic matrix materials to improve recyclability, use renewable sources, and reduce material costs. In this context, development biodegradable polymers for composites is considered one important strategies reducing environmental challenges. Here, axially oriented fibers incorporated in conforming matrices make up fi...

The preparation of fiber-reinforced phosphorus building gypsum composite materials (FRPGCs) is an important approach to enlarge the utilization phosphogypsum resources. Through reinforcing (PBG) with basalt fiber (BF), this article probes into effects length and content BF on working performance mechanical properties basalt-fiber-reinforced (BRPGCs) accesses toughness BRPGCs under bending loads...

The failure mechanisms of Oxide-Oxide ceramic matrix composites AS-N610 were studied at both room temperature and high using tensile fatigue tests with without lateral laminar notches. unnotched coupons had an average strength 423 MPa elastic modulus 97 GPa showing a perfect behaviour whereas the notched samples shown similar 425 (98 GPa) revealing pseudo-ductile behaviour. A reduction in oxide...

While a freestanding high-strength sheet metal subject to tension will rupture at a small strain, it is anticipated that lamination with a ductile sheet metal will retard this instability to an extent that depends on the relative thickness, the relative stiffness, and the hardening exponent of the ductile sheet. This paper presents an analytical study for the deformability of such laminate with...

The effect of chain packing on tensile properties was studied employing amorphous poly(lactic acid) PLA. It was found that the samples cooled in the temperature range from 60 to 80 °C, that is, slightly higher than the glass transition temperature Tg, showed ductile behavior with a low brittle-ductile transition temperature. Furthermore, the samples obtained by prolonged cooling at 56 °C also s...

A phenomenological material model is developed to understand the pseudo-ductile behavior of steel fiber reinforced high performance concrete (HPC) during failure. In that respect, an energy function formulated using additive composition a transversal isotropic elasto-plastic and phase-field representing individual fibers material, respectively. Comparing experimental data numerical results thre...

 Evaluate the impact on pipe performance and life expectancy of the transition (1991) from wall thickness class to pressure class designations in the manufacture and design standards for ductile iron pipes.  Study and compare historical failure rates of ductile iron pipes in a geographically diverse group of water utilities from North America and Australia.  Evaluate reliability and capabili...

The gravitational deformation of volcanoes is largely controlled by ductile layers of substrata. Using numerical finite-element modelling we investigate the role of ductile layer thickness and viscosity on such deformation. To characterise Ž .
