In the modelling of machining operations, constitutive models must consider the material behavior subject to high plastic strains, high strain rates, high temperatures and high heating rates. A new material model for AISI 1045, which captures time-de

Flat-ended projectiles were used to impact three distinct thicknesses of 2024-T351 plate. Ballistic limit velocities were determined, and optical microscopic examination revealed evidence o...

This paper investigates adiabatic shear bands (ASBs) in 2024-T351 aluminium and their effect on the mechanical properties and microstructure of this aluminium alloy. Using hat-shaped specimens in a split Hopkinson pressure bar (SHPB) and universal te

The protective performance of different armour steels and structural steels against the impact of an explosively formed projectile was investigated. For the tests the impact velocity of the EFP projectiles was kept constant at 1400 m/s. Machinely for

The presence and quality of welds in metallic structures has the ability to influence their likelihood of failure under dynamic loading. This investigation focused on characterising the behaviour of a welded aluminium structure. Samples were taken fr

Expansion of the family planning service in a municipal hospital resulted from a reassignment of personnel; the nurses role in this expansion is described. The nurses 4 functions include preparing the patient for the acceptance of family planning; th

Beside tension tests and measuring of Lankford coefficients (r-values), compression tests on small cubes in the sheet plane over a wide range of strain rates are also performed using special devices. The material behavior under shear loading is measu

The ductile failure behavior of materials is of great relevance for the modeling of forming and cutting processes, as the stable process parameter range is strongly influenced by the maximum deformation up to failure. Many publications show that the

This report describes the effort to develop a low-temperature rolling procedure for as-received AZ31B, a magnesium (Mg) alloy that contains approximately 3% aluminum and 1% zinc. In particular, we investigated the ability to roll AZ31B to thicknesses
