with the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. in this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of az31b. due to asymmetric and anisotropic behav...

Given the sophisticated nature of the blast phenomenon in relation to structures, it is of significance to accurately investigate the structure behavior under blast loads. Due to its rapid and transient nature, blast loading is one of the most important dynamic loadings on the structures. Since masonry materials are widely used as the partition and bearing walls in the existing and newly-built ...

The study evaluates the micronized poloxamers Lptrol micro127 (poloxamer 407) and Lptrol micro 68 (poloxamer 188) as lubricants in combination with the dry binders microcrystalline cellulose and spray-dried lactose. Magnesium stearate was employed as the comparative lubricant. The parameters under study included energy for friction, plasticity, ejection force, tensile strength of tablets, and d...

Tensile strength is a crucial parameter involved in the design and analysis of cemented paste backfill (CPB). The ability CPB to withstand tensile forces essential for stability backfilled stopes, particularly areas with high stress or deformation. critical used sill mats perform underhand cut-and-fill operations. This study presents novel technique that utilizes rectangular dog-bone specimens ...

The uniaxial thermomechanical behavior of a polycrystalline Fe-9%Cr-5%Ni-14%Mn-6%Si (all wt.%) shape memory alloy is investigated for both tensile and compressive stress states. The martensite start stresses measured upon tension and compression loading of austenite depend linearly on temperature, thus forming straight lines in the stress-temperature regime. The lines belonging to tension and c...

INTRODUCTION Biot’s theory of poroelastic solids [1] describes the behavior of fluids in porous materials and provides the biophysical basis for loadinduced fluid flow in bone. Applying this theory to bone, compression of the matrix causes an instantaneous increase in pore pressure within the matrix; to equilibrate this pore pressure gradient, fluid moves out of the pore spaces of the matrix un...

To study the failure modes, bearing capacity, ductility, and sleeve strain of grouted lapping connectors, 36 specimens were tested under uniaxial tensile load. The test results show that sleeves are longitudinal tension at beginning, which changes to compression in late stage loading, changing load increases gradually with lap length. force transmission path mechanical mechanism connectors anal...

The main contribution of this work is validating the Ludwick law to model nonlinear mechanical behavior in prediction critical buckling load elastic columns. loads specimens with different slenderness ratios were obtained by conducting experimental tests on flax/PLA columns pinned–pinned boundary conditions. modified parameters calibrated fit stress–strain curve tensile specimens. manufactured ...
