Strain Rate Effect on Tensile Behavior for a High Specific Strength Steel: From Quasi-Static to Intermediate Strain Rates
The strain rate effect on the tensile behaviors of a high specific strength steel (HSSS) with dual-phase microstructure has been investigated. The yield strength, the ultimate strength and the tensile toughness were all observed to increase with increasing strain rates at the range of 0.0006 to 56/s, rendering this HSSS as an excellent candidate for an energy absorber in the automobile industry...
متن کاملBrazilian Test for Tensile Failure of Anisotropic Shale under Different Strain Rates at Quasi-static Loading
Shale formations show obvious anisotropic characteristics in their mechanical properties due to pronounced bedding planes and natural fractures. This anisotropic behavior generally creates complex fracturing networks and is crucial to gas shale stimulation. Although much research has been done to study the anisotropic compression behaviors of shale with static and quasi-static strain rates, the...
متن کاملInfluence of High Strain Rates on the Mechanical Behavior of High-Manganese Steels
In this work, dynamic mechanical properties of three high-manganese steels with TRIP/TWIP or fully TWIP characteristics are studied. High strain rate experiments in the range of true strain rates between ~500 and 1800 /s are conducted using a dynamic torsional testing setup. All the three steels show a positive strain rate sensitivity in the intermediate range of strain rates (up to 500 /s). Bu...
متن کاملQuasi-static Evolution for a Model in Strain Gradient Plasticity
We prove the existence of a quasistatic evolution for a model in strain gradient plasticity proposed by Gurtin and Anand concerning isotropic, plastically irrotational materials under small deformations. This is done by means of the energetic approach to rate-independent evolution problems. Finally we study the asymptotic behavior of the evolution as the strain gradient length scales tend to ze...
متن کاملPlane Behaviour at High Strain Rates of a Quasi-Unidirectional E-Glass/Polyester Composite : Impact Application
Dealing with the plane behaviour of a composite quasi-unidirectional elementary ply made of E glasslpolyester, this paper contributes to the study of impact phenomena on ceramic/composite bi-layered targets. Firstly, a quasistatic modelisation of the elementary ply behavior, in plane tensile and plane shear, is presented. It allows a good description of the residual strains and of stiffness los...
