this paper aims at investigating the effects of weld nugget size and expulsion on the mechanical properties of low carbon steel resistance spot welds using tensile-shear test. mechanical performance of spot welds are described in terms of failure mode, peak load and failure energy obtained from the tensile-shear test. the effects of voids and porosity as well as electrode indentation associated...

background: heart failure is one of the chronic heart diseases and a debilitating condition of increased prevalence in the elderly. one of the important and non‑pharmacological strategies for improving clinical outcomes in these patients is promotion of the self‑care. background and social environment in which a patient is trying to control his disease is an important factor in the self‑care. t...

foundations behavior is affected by soil behavior which can vary from dilative to contractive depending on the stress level, particularly in dense frictional soils. the zero extension lines (zel) method has been generally developed to predict the foundations behavior. knowledge of soil behavior enables the zel method to predict the general and local shear failure modes. in this paper, a relativ...

background chronic heart failure (chf) is associated with unpredictably increased prevalence of hospital admissions. self-care is one of the most important aspects of management for patients with chf. self-care adequacy has led to increased satisfaction, independence in daily activities, reduced stress, and morbidity. objectives we aimed to assess the relationship between self-care behavior and...

in this paper, using numerical methods and test results, the behavior of reinforced concrete beams strengthened with fiber-reinforced polymers (frp) is investigated. in the numerical analysis, the concrete damaged plasticity model is used for considering the nonlinear behavior and strain softening of concrete. the abaqus finite element program is utilized for the analysis of 12 flexural beams s...

in this study, behavior of pin-loaded glass fiber reinforced with polyethylene laminated composites with different stacking sequence and different dimensions has been observed experimentally and stress analysis was performed using ansys software. the aim is to investigate stresses, failure strength and failure mode of composite laminates containing a pin loaded hole when the material exhibits l...
