The establishment of a simple engineering rule for predicting the fatigue failure concrete has been pursued over past decades. An energetic approach to matter seems be an attractive option that many researchers have embraced. In present work, authors attempt contribute such rule. particular, energy dissipation confined subjected shear cyclic loading is studied and quantified. For this purpose, ...

Introduction. Failure of the bone cement in a total joint replacement can lead to implant loosening and ultimately necessitate device revision. Establishing and maintaining the integrity of the polymethylmethacrylate (PMMA) bone cement is thus important to the long-term performance of cemented joint replacements. In particular, the fracture toughness or work to failure of the cement may play an...

nowadays, soil reinforcement using polymer elements have been investigated by a number of researchers in order to increase the load capacity of soils. reinforcing soils using fibers is a method of soil improvement, which offers a homogenous mixture in combination with soils, regarding their tensile strength. this combination maintains pressure loading capacity and properties in mutual resistant...

Abstract Using an innovative experimental set-up (Punch-Through Shear test), we initiated a shear zone (microfault) in Flechtingen sandstone and Odenwald granite under situ reservoir conditions while monitoring permeability fracture dilation evolution. The zone, which has cylindrical geometry, is produced by self-designed piston assembly that punches down the inner part of sample. Permeability ...

If little is known about the sample under test, ascertaining a quantitative material true stress–true strain relationship from a small punch test is not direct. Conventional inverse simulation methods have used experimental force–displacement curves that ignore the deformation shape of the punched sample. We present small punch test methodology and results that used experimental deformation sha...

AIM Experimental determination of the shear stress for punching meniscal tissue. METHODS Meniscectomy (surgical treatment of a lesion of one of the menisci) is the most frequently performed arthroscopic procedure. The performance of a meniscectomy is not optimal with the currently available instruments. To design new instruments, the punching force of meniscal tissue is an important parameter...
