3D Continuum Damage Mechanics Model with Permanent Strain
American Society for Composites 2018, 2018Most currently available material models for composites do not allow for permanent strain. For applications such as ballistic containment and energy absorption applications, this results in under predicting material performance. This study extends the Matzenmiller, Lubliner and Taylor (MLT) model, a continuum damage mechanics (CDM) based constitutive ...

Model for Resilient Modulus and Permanent Strain of Subgrade Soils
Transportation Research Record: Journal of the Transportation Research Board, 1998The resilient modulus and cumulative permanent strain of subgrade soils under anticipated repeated loading are important considerations for the design of a pavement against fatigue and rutting failures. A simple model was developed to evaluate the resilient modulus and accumulated permanent strain of cohesive subgrade soils under repeated loads.

Permanent Strains in Clay-Like Material During Drying
Drying Technology, 2009One of the characteristic features of clay-like materials is the change of their mechanical properties during drying as the moisture content is changed. At high moisture contents they are viscoelastic and then become elastic-plastic and finally brittle-elastic or even stiff.

Permanent Cap-rock Strain Measurement for a Thermal Development
SPE EOR Conference at Oil and Gas West Asia, 2014Abstract In a thermal development of a highly fractured carbonate the surface facilities are above the reservoir, and are sensitive to surface deformation. A coupled reservoir-geomechanical model has been history matched to synthetic-aperture radar satellite measurements of the surface uplift that occurred during the pilot, and this will

Experimental and Modeling Studies of Permanent Strains of Subgrade Soils
Journal of Geotechnical and Geoenvironmental Engineering, 2009Mechanistic-empirical pavement design guide for flexible pavements as per the AASHTO design guide requires characterization of subgrade soils using the resilient modulus ( MR ) property.

Permanent strains from cyclic variable-amplitude loadings
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1986Cyclic triaxial tests were performed on a well‐graded railroad ballast with a maximum particle size of 38 mm (1.5 in.). Samples were compacted in a split mold to reproduceable density states and subjected to repeated applications of compressive axial stresses.

The Permanent Strain in a Uniform Bar Due to Longitudinal Impact
Journal of Applied Mechanics, 1947Abstract A method is presented for predicting the final strained state of a long uniform bar or wire of ductile material that is subjected to a longitudinal impact of finite duration during which the impact stress is constant and exceeds the yield strength.

Permanent draft genome sequence of Geobacillus thermocatenulatus strain GS-1
Marine Genomics, 2014Geobacillus thermocatenulatus strain GS-1 is a thermophilic bacillus having a growth optimum at 60°C, capable of degrading alkanes. It was isolated from the formation water of a high-temperature deep oil reservoir in Qinghai oilfield, China. Here, we report the draft genome sequence with an estimated assembly size of 3.5Mb.

Simulating damage and permanent strain in composites under in-plane fatigue loading
Computers & Structures, 2005Fibre-reinforced composites are used in many fatigue-critical applications (wind turbine blades, aircraft components, leaf springs, ...). Due to their heterogeneous and anisotropic nature, their fatigue behaviour is rather complex and several damage mechanisms can develop during fatigue life.

Permanent strain and damage formulation in forming processes of filled-elastomer materials
International Journal of Material Forming, 2008The rubbery environments present the same mechanical behaviour as hyperelastic or viscohyperelastic material. Regarding the filled-elastomers, the high degree of deformability often generate microscopic and voluminal defects leading to the creation of micro-cracks inside the structure.
