Modeling the Forces of Cutting With Scissors [PDF]
IEEE Transactions on Biomedical Engineering, 2008 Modeling forces applied to scissors during cutting of biological materials is useful for surgical simulation. Previous approaches to haptic display of scissor cutting are based on recording and replaying measured data. This paper presents an analytical model based on the concepts of contact mechanics and fracture mechanics to calculate forces applied ...

Cohen forcing and inner models [PDF]
Mathematical Logic Quarterly, 2020 AbstractGiven an inner model and a regular cardinal κ, we consider two alternatives for adding a subset to κ by forcing: the Cohen poset Add(κ, 1), and the Cohen poset of the inner model . The forcing from W will be at least as strong as the forcing from V (in the sense that forcing with the former adds a generic for the latter) if and only if the two

Actuator line model using simplified force calculation methods [PDF]
Wind Energy Science, 2023 To simulate transient wind turbine wake interaction problems using limited wind turbine data, two new variants of the actuator line technique are proposed in which the rotor blade forces are computed locally using generic load data.
