- The K factor is the ratio between the distance from the neutral bending line to the innerpress brakebending radius and the material thickness. The calculation formula of K factor is: K factor = δ/T The Y factor is determined by the K factor. - The Y factor is the ratio of the ne...
Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in Figure 1. We are going to review three bending scenarios with three different bending angles; 60, 90 and 120, and we will calculate K-Factor, Bend Allowance and Bend Deduction for them. The bending tool has ...
To calculate the bend allowance, the K factor, and the derived coefficient called the Y factor, insert the thickness and initial length of the sheet into the cells on the left. After bending the sheet, insert the inner radius, and flanges A and B. Bending angle is 90°. ...

The mode I fracture toughness,KIwas determined using the peak load, the non-dimensional stress intensity factor and the specimen dimensions [35]. For the SCB specimen, the equation is given as under [36].KI=YP(πa)2RtwhereYis a non-dimensional stress intensity factor,Pis the load,ais the...
In writing the plastic bending section for our (soon to be released) free textbook I started to look into the origin of the shape factor for the cross section of a beam for plastic bending. It is explained in Bruhn and in other references but in the past I have always just used the ...
