Deep and high-stress mining results in stress transfers onto the previously placed backfill, mines have recorded several MPa induced backfill stresses. Understanding backfill-rock mass interaction is therefore critical. Previous work considered tabular ore bodies undergoing primarily one-dimensional compression showed how reaction curves could be estimated from oedometer laboratory test results...

INTRODUCTION Articular cartilage (AC) is an inhomogeneous, anisotropic and multiphasic composite. Depth-dependent strain distribution in full thickness AC has previously been investigated with optical methods (Guilak, 1995; Schinagl, 1997; Wang, 2003). Depth and time-dependent compressive strain has been predicted with theoretical models (Li, 2000; Wang, 2001). Most recently, Electronic Speckle...

Abstract It was fairly accepted to interpret soil behaviour at the microstructural level by utilising effective degree of saturation instead total in stress equation for unsaturated fine-grained soils. However, this interpretation pure sands under-represented literature. On basis shear strength evolution with suction, paper reports a series experimental tests evaluate use fine sands. The compri...

Abstract The research includes a new model proposed for the stress-strain relationship of unconfined concrete in compression valid normal and high strength concrete. A wide range experimental data with varied lab circumstances has been used fitting other verifying model. It is noted that current good agreement both its ascending descending branches Depending on mean average values to calculated...

Understanding and modelling liver biomechanics represents a significant challenge due to the complex nature of this organ. Unfortunately, there is no consensus on liver viscoelastic properties, and results are strongly dependent on sample type and status, adopted testing method, and testing conditions. Standard force-triggered tests (e.g. step response or dynamic mechanical tests) necessitate a...

To facilitate pavement design, the new proposed mechanistic-empirical pavement design guide recommends the resilient modulus to characterize subgrade soil and its use for calculating pavement responses attributable to traffic and environmental loading. Although resilient modulus values could be determined through laboratory testing of actual subgrade soil samples, such testing would require sig...

Tremendous quantities of reservoir deposited sediments are required to be dredged regularly to maintain the storage capacity of the reservoir. The reservoir dredged material (RDM) can be utilized as construction material after admixing with additives such as cement and fly ash thereby improving its strength characteristics. This research paper presents results of laboratory investigation carrie...

This study presented the overview on behavior of bentonite-sand mixture used in high level radioactive waste disposal. Both unconfined compression test and triaxial were conducted out that unsaturated-saturated samples applied temperature effect below 100 degrees Celsius. Unconfined compressive strength was determined with various temperatures different relative humidity for unsaturated specime...

Water susceptible properties of subgrade soils play important role in the structural design of highways. In this research study laboratory investigations were conducted on subgrade soil samples for determining the influence of water susceptible properties on Natural moisture content, Optimum moisture content, Compaction, California Bearing Ratio (CBR)-soaked and unsoaked, and Unconfined Compres...

Motor vehicle collisions can result in life threatening liver injuries. Dummies are utilized to study injury in motor vehicle collisions; however, no crash test dummies are currently equipped to represent individual solid organs. This has increased the use of finite element models to help reduce these injuries; however, accurate material models need to be established to have accurate injury ass...
