Progress report
As demonstrated in the literature review extensive research of the relevant publications in the field has been undertaken. These sources have provided me with background information allowing me to develop my knowledge about dome structures. My computation competence has developed through the completion of both exercises 1 and 2.
Exercise 1 is a simple project outlining the basis of how the PASHA and LEASH run. In order to continue to use these programs, I must verify the results reflect reality. Exercise 1 requires analytical solutions based on Michael Rotter's, "Bending Theory of Shells for Bins and Silos", (2009) in order to validate the use of the software. Both the analytical and computational results fell within acceptable margins of one another validating the continuation of the software for analysis.
The deflected shape is shown below as follows the expected trend. (Note for this analysis a height of maximum 3 lamda has been used in order to capture the most affected region, anything beyond this point is irrelevant for this analysis).

Exercise 2 extends the use of the software for a spherical dome, displaying results from several scenarios, examining the effects of different boundary conditions on the stresses throughout the structure. Initially it only considers the application of uniform pressure but develops to include the self weight of the structure.
After the completion of data input which is generally based on a yes no basis, PASHA creates a file containing the corresponding inputs analytically. Small alterations can be made to this file when undergoing another run. In order to do this, I have annotated the file identifying the meaning behind each input shown, allowing quick and accurate changes to be made.
I am currently slightly behind the target set out in my Gantt chart , displayed in the project planning section due to technical reasons with LEASH. I will hopefully have this issue resolved shortly which will bring me back on target. I aim to continue to adhere to the schedule of events in order to produce a successful thesis.
