This research investigates the effect of post-cure time on residual stresses in laminated composites. Laminated composites were made of T300 carbon fibers and epoxy resin. The post-cure process was carried out at the constant temperature of 120 °C for 6 and 12 hours for two specimens. The slitting method was employed to determine through-thickness residual stress distribution of the composite l...

Mathematical models for optimization can help companies optimizing their production and planning processes and therefore to reduce costs and increase quality. But applying such models effectively is challenging. Developers need expertise in mathematics and skills in software development to implement them. Furthermore optimization algorithms are inherently computationally very intensive. Paralle...

various researches have been carried out about benefits of accounting information and their influence on decision making of financial statements users. for example, many researches have examined the relationship between accounting variables and stock returns or stock price. this study determines and compares the relative and incremental content of accounting variables, too. for this purpose, th...

This study outlines the recent developments in metal forming processes, focusing mainly on shearing process. A summary of background process is given to give perspective how such a has changed over time. It explains what operations are and operated forming. While also outlining difference between shearing, slitting, punching, notching, blanking advantages disadvantages detailed. Different types...

the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

Many destructive methods for measuring residual stresses such as the slitting method require an inverse analysis to solve problem. The accuracy of result well uncertainty component (the model uncertainty) depends on basis functions used in solution. use a series expansion solution was analysed previous work particular case where orders grew consecutively. present presents new estimation and imp...
