Comparative Study on the Test Method for Tensile Elastic Modulus of Rock Materials [PDF]

open access: yesAdvances in Civil Engineering, 2019
Rock material has different mechanical behaviors under compressive and tensile loading. Correspondingly, there are two types of elastic modulus: compressive elastic modulus Ec and tensile elastic modulus Et, respectively.

Calculation Derivation and Test Verification of Indirect Tensile Strength of Asphalt Pavement Interlayers at Low Temperatures [PDF]

open access: yes, 2021
When the direct tensile test is adopted to determine the interlayer tensile strength of the asphalt pavements, specimen separation or internal cracking often occurs at the bonding area of the loading head, rather than at the interlaminar bonding ...

A Direct Tensile Strength Testing Method for Concrete from Existing Structures

open access: yesCivilEng, 2023
Tensile strength is a crucial property for the function, safety and durability of all concrete structures. The general procedure to assess the tensile properties of concrete from existing structures is to perform indirect tests and predict the tensile ...

Methods and Points of Attention for the Direct Tension Test on Rock

open access: yesJournal of MMIJ, 2016
Compared to uniaxial or triaxial compression tests on rocks, direct tension tests on rocks are not common in practice. As is well known, the reasons are because underground rock masses are usually under compressive stress state and/or because the direct ...
