    Defining matrix variable to get numerical solution to the Winkler foundation differential equation

    Hi Greg, I tried to implement a 'for loop' and defined the range index for the v (=distance x) and bending moment M, BUT it still won't assign the values to the matrix variable M (pls see below). Not sure why the matrix variable M = zero, unlike the results of the 2nd order derivatire of the...

    Defining matrix variable to get numerical solution to the Winkler foundation differential equation

    Following the solution to the differential equation for the deflection curve of a beam on an elastic foundation, am trying to get the bending moment M and shearing force V based on the 2nd- and 3rd-order derivatives. I can come up with values based on the derivative expression BUT am unable to...

    Counteracting with vibro hammer process to correct longitudinal lean during sheet pile driving

    Hi to ALL, I would just like to ask for tips and recommendations to do the above process to avoid damage to the interlocks during driving. We're following NASSPA sheet pile guide, and did the following with these results: - pulled with wire rope to reduce longitudinal lean from 2.7% to 2.2% -...
