1. High strain-rate experiments using high-speed photography
Abstract : In many technical processes, material is deformed under conditions that contain high strain rates. Examples of such processes are collisions, impact, penetration, metal forming and crack propagation. Constitutive models including viscoplasticity have been proposed for these kinds of situations.

2. High strain rate deformation of Alloy 718
Abstract : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable it is possible to have a large variety of strength depending on microstructure. READ MORE

3. Frictional studies and high strain rate testing of wood under refining conditions
Abstract : When producing thermomechanical pulps (TMP), wood chips and fiber material are loaded mechanically in a disc-refiner to separate the fibers and to make them flexible. In the process, much of the energy supplied is transferred to the fiber material through cyclic compression, shear and friction processes. READ MORE

4. Monotonic and Cyclic Plastic Deformation of High-Strength Aluminium Alloys
Abstract : Dynamic strain ageing (DSA) and dynamic precipitation (DP) are two, closely interrelated, phenomena arising from the dynamic interaction between mobile solute atoms and dislocations. The occurrence of DSA and DP is confined to specific ranges of strain rate and temperature, and aluminium alloys are generally prone to experience DSA and DP already at ambient temperatures and conventional strainrates.

5. Insight into Coro-Carotid atherosclerotic disease in patients with acute coronary syndrome
Abstract : Background: the arterial tree branches in different parts of human body are sharing the histological and physiological features. Atherosclerosis is a systemic arterial disease, hence is expected to affect to affect more than one arterial system with similar pathologic manifestations. READ MORE
