Volume 49, Issue 2 , December 2017, , Pages 63-101

https://doi.org/10.22059/jac.2017.7978

Abstract
  Sugeno-Weber family of t-norms and t-conorms is one of the most applied one in various fuzzy modelling problems. This family of t-norms and t-conorms was suggested by Weber for modeling intersection and union of fuzzy sets. Also, the t-conorms were suggested as addition rules by Sugeno for so-called  ...  Read More

https://doi.org/10.22059/jac.2013.7670

Abstract
  In this paper a special sandwich panel with a sinusoidal core under distributed load on upper and lower plates has been studied. By drawing free body diagrams, and using energy method and Castagiliano theory the forces and moments involved in the core has been determined. Then, the stresses, normal and ...  Read More
