Experimental investigation for the dynamic characteristics of short natural fiber reinforced composite materials Indian J. Eng. Mater. Sci. (IF 0.615) Pub Date : 2022-07-06 Kartikay Singh Pawar, Ashok Kumar Bagha, Shashi Bahl, Manoj Kumar Agrawal
The study of mechanical and dynamic characteristics of composite materials is important. Vibration is one of the major problems faced because of the uncertainty and the disturbances due to its surroundings. For composite being used in the structures like aircraft, automobiles, railway coaches and buildings it should have sound mechanical and dynamic characteristics. Many researchers have been interested

Evaluation of wind pressure on the low-rise buildings and surrounding terrain under the influence of tornadolike vortex induced aerodynamic loads Indian J. Eng. Mater. Sci. (IF 0.615) Pub Date : 2022-07-06 Mohammed Moizuddin, Rajesh Goyal, Nakul Gupta, Masahiro Matsui
Wind loading on buildings caused by straight line boundary layer winds has been thoroughly investigated in the past. The effects of vortex loading on structural projections will induce crosswind loads and torsional loads on low rise building which has severe dynamic resonant effect not only on the structural projections but also on over all structural elements of a building. These structural projections

Investigation of micro-hardness of H11 die steel using composite material electrodes in EDM Indian J. Eng. Mater. Sci. (IF 0.615) Pub Date : 2022-07-06 Parveen Goyal, Rajesh Kumar, Sanjeev Kumar, Bharat Singh
Electrical Discharge Machining (EDM), a non-traditional material removal process has been well recognized for its ability for precision machining of electrically conducting hard materials. Repetitive heating and cooling of the workpiece surface during the machining make the surface hard. During this process, the transfer of material into workpiece surface due to diffusion of material from the tool

Filler powder free joining of SAF 2507 using selective microwave hybrid heating technique Indian J. Eng. Mater. Sci. (IF 0.615) Pub Date : 2022-07-06 Parminder Singh, Deo Raj Prajapati, Shankar Sehgal
Microwave Hybrid Heating (MHH) based joining of super duplex stainless steel (SAF 2507) with cross-sectional dimensions 3.5 mm ×3 mm has been carried out for the first time by using a microwave applicator of 900 W operated at 2.45 GHz for 400 s. Graphite rods have been used instead of traditionally used charcoal powder to serve as susceptor material. Graphite rods are good susceptor of microwave radiations

Thermal performance evaluation of cellulose fibre as building insulation material Indian J. Eng. Mater. Sci. (IF 0.615) Pub Date : 2022-07-06 Ravinder Kumar Pal, Parveen Goyal, Shankar Sehgal
Space cooling has utilized lots of electricity in summers which has to be reduced by insulating inside of buildings. This has potential to reduce the environment pollution caused by higher expenditure of energy. The present work has the scope to evaluate thermal performance of a test model house providing cellulose fibre based cardboard insulation and compare the performance with an uninsulated model
