2.3.4.2
tensile strength (related to specimen width)
T
tensile force per unit width carried by a specimen at any given time in a short-term test
Note 1 to entry: Unit is expressed in kN/m.
2.3,4,2.1
tensile strength (related to specimen width) at failure
tensile strength at which the test specimen ruptures
2.3.4.2.2
maximum tensile strength (related to specimen width) Tmas
maximum tensile strength sustained by the test specimen during a tensile test
2.3.4.2.3
tensile modulus
I
ratio of the change In tensile stress or strength of a geosynthetic to the corresponding change In elongation
Note 1 to entry: Tensile modulus is expressed in MPa or kN/m.
2.3.4.3
preload
small load equal to 1 % of the expected maximum load, enabling initial gauge length and strain zero to be determined tinder re-producible conditions
2.3.5 Seaming or attaching of GTX or GTP
2.3.5.1
connection
local or linear attachment of dissimilar geosynthetics or of a geosynthetic and another material
2.3.5.2
joint
local or linear attachment of adjacent rolls of similar geosynthetic
2.3.5.3
bond
areal attachment of the elements of a geocomposite to each other
2.3.5.4
maximum joint or seam strength Timix
maximum tensile strength of the seam formed by joining two or more sheets
Note 1 to entry: Unit is expressed in kN/m.
2.3.5.5
joInt or seam efficiency
ratio of the joint or seam strength to the tensile strength o[the material measured in the sa me direction Note I to entry: Unit is expressed In %.
2.3.6.2
friction interaction (efficiency) coefficientfs,csY
ratio between the tangent of the friction angle between soil and GSY, and the tangent of the frictionangle of the soil
2.4Other terms2.4.1
machine directionMD
direction of manufacture of a geosynthetic product (the warp direction for woven geotextiles)
2.4.2
cross-machine directionCMD
direction perpendicular to the direction of manufacture of a geo-synthetic product (the weft directionfor woven geotextiles)
2.4.3
design life
period of time from the start of installation to the point where the material no longer fulfils its requireddesign properties in order to perform its function within defined limits
2.4.4
peel test
tensile test of a bond, join, or connection in which two components are separately clamped and onecomponent is peeled away from the other in order to determine peel strength
2.4.5
tensile shear test
tensile test of a bond, joint, or connection in which two components are separately clamped and load isapplied in the plane of the product in order to determine tensile shear strength
