Indian standard Code-IS:456-2000 and Eurocode EC:02-2004 for the design of the concrete structure is limited to the concrete with compressive strength of 55 MPa and 90 MPa respectively. For defining the stress block parameters and for the design of concre... see more

EXCAVATION OF TUNNELS PRODUCES A REDISTRIBUITION OF STRESSES AND INDUCES DEFORMATIONS IN THE ROCK MASS AROUND THE TUNNEL’S CROSS SECTION. IN THE CASE OF ELASTO-PLASTIC BEHAVIOR OF ROCK MASS, PLASTIC ZONES MAY APPEAR. IT IS IMPORTANT TO QUANTIFY THE INFLUE... see more

Abstract. It was known that soil behavior is dependent upon the history of loading and exhibits hardening behavior when deformed plastically. This paper presents a formulation of mixed hardening multisurface hyperplasticity model with stiffness factors of... see more

The present investigation was undertaken to improve the performance of carob cuttings in terms of adventitious roots formation and hardening using arbuscular mycorrhizal fungi (AMF). Softwood cuttings were treated with 5000 mg L-1 of indole-3-butyric acid... see more

A thorough investigation has been carried out on the Al-12Si-1Mg-1Cu-1Ni automotive alloy considering different properties, specially mechanical properties associated with true stress and true strain with Zr addition of trace amount. A commercially availa... see more

The influence of three grades of purity of commercial aluminium on the evolution of the major mechanical characteristics: stress and strain energy, hardness, elongation and stress coefficients, resilience and microstructure have been studied. It was found... see more

It is shown that when modeling the processes of forging and stamping, it is necessary to take into account not only the hardening of the material, but also softening, which occurs during hot processing. Otherwise, the power parameters of the deformation p... see more

Motivated by the prospective uses of plastically compressible materials such as, metallic and polymeric foams, transformation toughened ceramics, toughened structural polymers etc., the present authors investigate the crack-tip radius effect on fatigue cr... see more
