3D printing of mortars and concretes with industrial waste
Agenda 2030 is a plan of action adopted by the United Nations in 2015 to promote sustainable development and address global challenges such as poverty, inequality, and climate change. It includes 17 Sustainable Development Goals (SDGs) that aim to transform the world by 2030 through economic, social, and environmental sustainability [1]. In relation to use…
Multi-material additive manufacturing in construction
Additive manufacturing (AM) is a cutting-edge technique for producing mechanical and structural components that is a key player in the fourth industrial revolution, the digital industrial transformation. AM technology has gained widespread popularity in recent years due to its unique advantages, such as the ability to manufacture parts with complex geometry and optimal topology, as…
Bending
In this video I will talk about bending and effect of it on materials (in Persian).
DIC with GOM correlate
In this video, I will be demonstrating how to measure strain and displacement using the DIC technique in GOM Correlate software. Please note that the video is recorded in Persian language.
Cold spray additive manufacturing
The cold spray technique involves accelerating micron-sized particles to high speeds of 300-1200 m/s, resulting in plastic deformation upon impact with the substrate and adherence to its surface. The spraying nozzle is scanned along the substrate to achieve uniform thickness. Cold spray can deposit various materials such as metals, polymers, ceramics, composites, and nanocrystalline powders….
MSc
I am truly delighted to announce that finally, after 3 years of hard work and dedication, I successfully defend my MSc thesis entitled “Experimental study of the strain ratcheting in additively manufactured 316L steel”. I highly appreciate Prof. Mostafa zeinoddini and Dr. Mehdi Ezzati for their collaboration, advice and help during this long and rigid path. I…
What is Ratcheting?
A progressive accumulation of plastic strain, called strain ratcheting, occurs in ductile materials, subject to asymmetrical inelastic cyclic stressing. Ratcheting is characterised by a shift in the stress-strain hysteresis loop along the strain axis and incremental inelastic deformations. The ratcheting phenomenon is of paramount importance in the design procedure of systems, which undergo inelastic cyclic…
Application of Digital image correlation in cycling loading
DIC is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains, and it is widely applied in many areas of science and engineering. [1] This new testing procedure can help to obtain more…
Axial loading
In this video I will talk about axial loading and effect of this loading on materials (in Persian).
Stress and strain
In this video I will explain the meaning of stress and strain and kind of them. Also I will Solve several problems (in Persian).
