Compression test

In this paper, the effect of continuous carbon fibers (CCF) on the stiffness of 3D printed frames is investigated. Fused deposition modelling (FDM) technology is employed to build three typical frames with 15% of CCF and 85% poliamide 12 which is combined 10% short carbon fibers (PA12-CF) for compress testing.

This paper presents the experimental study on onedimensional compressibility behavior, soil water characteristic and soil shrinkage behavior of slurry Amberger kaolin. The volume change behavior of sample due to the suction and that due to applied vertical stress demonstrated a similarity within the saturation domain.

This study investigated experimental bearing capacity of corroded reinforced concrete beams. Six testing beams were made of concrete having compressive strength of 25 MPa, with the dimensions of 80 x 120 x 1200 mm. They were divided into two groups depending of tension reinforcement ratio.

In the present study, from recent experimental results of asymmetrical loading tests on SFRC beams without stirrups, three NLFE models have been validated and further developed to evaluate the impact that the ratio of shear span-to-depth (a/d) and the compressive strength of steel fiber concrete (SFC) have on the shear behavior and shear strength of SFRC beams without stirrups.

By using an extensive three-dimensional discrete element method, we numerically investigate the effects of lightweight particle content on the mechanical strength of the cylindrical aggregates, randomly composed of two different groups of primary particles: light (low stiffness) and heavy (high stiffness), and the stress contribution of the heavy-heavy, light-heavy, and light-light interactions on the mechanical behavior of such aggregates, subjected to the compression test by using a constant downward velocity.

We numerically study the effects of the size polydispersity and the friction coefficient on the compressive strength of wet granules under a diametrical compression test by using discrete element simulations. The numerical method is coupled with the capillary cohesion law which is enhanced by the cohesive forces between grains in the pendular regime.

Phép đo sức bền cơ nhiệt TMCT (Thermal Mechanical Compression Test) được ứng dụng để đo nhiệt độ hóa mềm Tg-r (glass-rubber transition temperature) của bột gạo ở khoảng ẩm độ thấp từ 2.4-19.5 % cơ sở ướt. Kết quả cho thấy Tg-r tăng khi ẩm độ giảm. Nhiệt độ hóa mềm của gạo đo bằng phép đo sức bền cơ nhiệt tương tự với các kết quả được trình bày trong các nghiên cứu khác sử dụng các phương pháp nhiệt lượng kế quét vi sai DSC (Differential Scanning Calorimetry), phân tích cơ nhiệt (TMA-Thermo-mechanical Analysis) và phân tích cơ nhiệt động (DMTA-Dynamic Mechanical Thermal...

Withholding further diagnostic testing and anticoagulant treatment in those patients with an unlikely clinical probability and a normal D-dimer level, which constitutes 30–50% of all referred patients, is safe. The remaining patients need to undergo (repeated) compression ultrasonography. An alternative approach is to perform a whole-leg imaging test on the day of referral. The advantage of this approach is that it eliminates the need for a repeat test (and may even obviate the probability assessment and D-dimer testing).

A typical geotechnical engineering project begins with a site investigation of soil and bedrock on and below an area of interest to determine their engineering properties including how they will interact with, on or in a proposed construction. Examining of soil properties, especially in shear stress, is indispensable to understanding of the area in or on which the construction will take place. There are two main kinds of the test: direct shear test and triaxial test.
