In this work the quasi-static response of thermoplastic butt-joint stiffened beam in bending conditions is modeled. In these panels, the stiffener is connected to the skin by a shortfiber reinforced filler. Although this type of connection performs very well in a pull-off loading (fracture loading is 10 times higher than welded connection), optimization is required regarding its impact performa...

The glycosaminoglycan of decorin, dermatan sulfate (DS), has been suggested to contribute to the mechanical properties of soft connective tissues such as ligaments and tendons. This study investigated the mechanical function of DS in human medial collateral ligaments (MCL) using nondestructive shear and tensile material tests performed before and after targeted removal of DS with chondroitinase...

One of the parameters identified as influencing the structural response of buildings is the dynamic Modulus of Elasticity of masonry. The Longitudinal Vibration Test Method and the Ultrasonic Pulse Methods were developed for the dynamic testing of concrete specimens. These two dynamic procedures are to be tested on masonry prisms to provide a verification of the methods. The first aim of this p...

Thick bonding wires are used in modern power modules as connectors between integrated circuits, carrying current from one circuit to another. They experience high values of current, which generates heat through Joule heating and can lead to various failure mechanisms. Typically used wire materials in industry are aluminum (Al), copper (Cu), and intermetallic compounds of Cu-Al. They are broadly...

Shale formations show obvious anisotropic characteristics in their mechanical properties due to pronounced bedding planes and natural fractures. This anisotropic behavior generally creates complex fracturing networks and is crucial to gas shale stimulation. Although much research has been done to study the anisotropic compression behaviors of shale with static and quasi-static strain rates, the...

This article deals with a static and quasi-static load using the maximum power of hydraulic pump. Additionally, coefficients for partially embedded rock bolts were determined. The laboratory tests included 2.2 m long bolts, which segmentally on lengths 0.05 m, 0.3 0.9 tested. To fix ribbed bolt rods in steel cylinders, resin cartridges length 0.45 used. main aim research was to determine load-d...

Injections bolts were initially conceptualized to repair riveted connections in bridges with long service lifetime and now they are widely used steel composite structures. Injecting steel-reinforced epoxy resin bolted oversized holes is a novel approach enable fast easy assembly of structures while limiting slip between the components. The performance these shear connectors mainly dependent on ...
