This work presents the effects of strain rate on the tensile properties and fracture morphologies of AHSS-DP 350/600 subjected to LSP. Fatigue crack growth test was performed to evaluate fatigue behavior in the metallic plate of AHSS-DP350/600. However, this material is used in automobile industry and enhancing it fatigue resistance is a challenge in material engineering. In order to evaluate a...
abstract pragmatics is the study of communicative action in its sociocultural context. communicative action includes not only using speech acts (such as apologizing, complaining, complimenting, and requesting), but also engaging in different types of discourse and participating in speech events of varying length and complexity. the present study aimed to investigate the assessment of pragm...
The poor durability of concrete bridges throughout the US is an increasingly large concern for highway transportation authorities. With decreasing budget allocations for infrastructure maintenance, rehabilitation, and replacement, the need for greater durability is apparent. A main source of this poor durability is leaking mechanical expansion joints between adjacent simple spans of multi-span ...
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
In this study, age hardenable material Aluminum alloy Al-7075-T6 (aged) was investigated for weldability. Al-7075-T6 plates were subjected to Al-7075-0 heat treatment and were joined with different welding parameters by means of friction stir welding method. After Joining, the parts which were subjected to tensile and bending tests were examined. As a result of the studies, it was observed that...
The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. ...
Objective(s): Tissue engineering represents a new approach to solve the current complications of the heart valve replacements by offering viable valve prosthesis with growth and remodeling capability. In this project, electrospinning and dip coating techniques were used to fabricate heart valve constructs from medical grade polyurethane (PU). Methods: Fir...
