Abstract: Material behavior in wires of 1100 aluminum subject to tensile impact loading is examined. Room temperature behavior is observed over the entire range of the stress-strain relation by observation ...

Abstract: The mechanical behavior of metals subjected to uniaxial tensile impact at elevated temperatures is reported. Tests were conducted on annealed 1100 aluminum at 200, 350, 550, and 800 deg F; ...

Abstract: The mechanical behavior of metals subjected to unaxial tensile impact at room temperature is reported. Tests were conducted on 1100 aluminum subjected to light and to heavy cold working; 2024 ...

Abstract: For several types of excitation of one-dimensional elastic-plastic stress waves in a rod, unloading waves propagate which interact with the loading waves. The moving boundary at which this ...

Abstract: When a thin, elastic-plastic wire is transversely impacted, both longitudinal and transverse loading waves propagate. For certain types of excitation, unloading waves also propagate, and they ...

Abstract: In this second part of a three-part report, we consider the mechanical behavior of 42 fresh human cadaver lumbar motion segments in compression, and in anterior, posterior, and lateral shear. ...

Abstract: Results are reported from an experiment involving photographic observation of constant-velocity transverse impact on long wires of annealed pure copper, two pure aluminums, and an aluminum alloy. ...

Abstract: A two-dimensional, sagittally-symmetric biomechanical model was developed to analyze the joint moments required to stabilize the trunk in a seated, dynamic, weight-moving task. Kinematic and reaction ...

Abstract: A simple axisymmetric finite element model of a human spine segment containing two adjacent vertebrae and the intervening intervertebral disk was constructed. The model incorporated four substructures: ...
