In this paper attempts have been done to create a mortar with relatively high uniaxial compressive strength (UCS), easy casting, high flexibility, instant hardening, low cost and easy availability. The main use of this material is to physically model the mechanical behavior of jointed rock-like blocks. The effect of four parameters such as joint roughness coefficient (JRC), bridge length (L), b...

Abstract Damage is a common condition in ancient timber structures, whose influence on the mechanical properties of structures cannot be ignored. To study damaged hoop head mortise-tenon joint, four specimens with shrinkage gauge, including one intact joint specimen and three artificial simulated specimens, are designed, fabricated this paper by regarding global damage degree column axial force...

The traditional tenon and mortise joint has low processing efficiency a weak theoretical basis, making the structure easy to deform damage, reducing safety, increasing waste of resources. This study aims determine optimum dowel center spacing parameter for chamfered-joint components maximum value strength joints loaded into bending tensile strength. In this study, an integrated optimization met...

statement of problem: there are controversial reports regarding physical and mechanical properties of resin composites and glass ionomer cements. some revealed higher strength and hardness for resin composites while others showed a comparable value for glass ionomer cements. evaluation of mechanical properties of different types of resin composites in comparison with resin modified glass ionome...

due to the existence of fibrous materials such as plastic fragments, the strength anisotropy of municipal solid waste (msw) materials is the main source of differences between their mechanical response in direct shear and triaxial apparatus. as an extension of earlier research on the mechanical behavior of msw using a large traixail apparatus, results presented in shariatmadari et al. [1] and k...
