This paper aims to investigate experimentally and using finite element analysis the performance of using three-dimensional printing technology to produce a composite sandwich panel that is made of the high-flexible core as well as with high stiffness upper and lower surfaces made of a glass fiber reinforced composite filament. There are many advantages of using sandwich structures in many applications, especially the aerospace field, where the high stiffness to strength and the lightweight is the most preferred in such applications. The conventional manufacturing methods that are used to produce sandwich panels are limited to particular core geometry, whereas manufacturing a composite core is not possible by these traditional production methods. So by using additive manufacturing technology, it becomes more applicable to design a combination of different geometries and materials to achieve properties that have never been made before, especially combining flexibility and high energy absorption keeping high strength to failure. A central deflection to a length of 0.26 is observed within the elastic zone, a remarkable ratio in beams that reflects the three-dimensional printed sandwich beams’ capability with a highly flexible core to absorb energy that would open doors for many industrial applications that is attributed to the lowest flexural rigidity (167E-3Pa · m4) of the sandwich by using the TriHex infill pattern. In contrast, the Gyroid infill structure could afford the highest central load (0.264 kN). At the peak load applied on the sandwich beam, a maximum error of 5.4% is estimated by finite element analysis lower than the experimental values.
The word Development is devious and captivating, however, the development path is perplexed. In most cases, the governments try to attain economic, military, technological, and infrastructural development, whereas, the power centers evade investing and working on issues of Human Development. The governments of countries like Pakistan strive to shuffle the attentiveness of the world by spending a huge amount on building the roads, on bridges, and transportation and in maximization of arms and ammunition. Human development in Pakistan has always been neglected due to various reasons. A huge population of almost a 22million having as low as 154th (out of 189 countries) position in the human development index. The patriarchal system has created the social and cultural environment that is supporting persistence male domination, remains the major obstacle in the intellectual, social, and economic growth of women. This paper addresses the conceptual and methodological aspects of human development and women’s empowerment in Pakistan, it explains the challenges and trends concerning women’s empowerment throughout Pakistan’s history, specifically in key areas such as individual, education, and health, economic and political participation, and especially Women’s limited and controlled mobility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
