The extended Linear Matching Method (LMM) is successfully applied in this study for the ratchet limit analysis of circumferentially welded pipes containing a circumferential

The complexity of ratchetting means that analytical solutions are rare, and thus incremental Finite Element Analysis (FEA) is widely used. Incremental FEA can only show

Because the numerical procedure presented calculates the strict shakedown limit and limit loads, with various levels of loading also calculated in between

Early studies in this tradi- tion found that some emotional expressions trigger complementary emotions in social perceivers: fa- cial displays of anger enhance fear conditioning

The proposed redesigned solar cell device structure has several advantages: (i) it absorbs more sunlight and hence creates more photoexcitons, (ii) it virtually increases the
