Deflections and Moments in Rectangular Plates

Posted on August 9, 2020 by

Following a question here I have compared tabulated coefficients for deflections and bending moments in a rectangular plate with results of a Strand7 analysis using 8 noded plate/shell elements.  The results are summarised below, and in a spreadsheet which also … Continue reading →

Dancing Pendulums Revisited

Posted on April 12, 2020 by

I have previously posted on Dynamically Defined Dancing Pendulums, using the Strand7 FEA program to generate the motion of a series of pendulums of varying length.  I have now updated that video using the latest Beta version of the program (Rel … Continue reading →

Column buckling under multiple loads

Posted on January 20, 2020 by

Following another buckling discussion at Eng-tips I have modified my Frame4-buckle spreadsheet to allow input of multiple axial loads at any point along the column, along with any number of sections with different section properties.  Background on the method used … Continue reading →

3D Frame with zero stiffness hinges

Posted on April 9, 2019 by

The previous version of 3DFrame allowed for spring releases at beam ends, but if the release stiffness was entered as zero it was treated as a rigid connection for that freedom.  Effectively zero stiffness releases could be modelled by entering … Continue reading →
