SDOF Analysis of Blast Loaded SC Panels in Two-Way Bending

<p>This package contains six MATLAB programs for conducting single-degree-of-freedom (SDOF) dynamic analysis of blast loaded steel-plate composite (SC) two-way panels. The programs can be used to run a SDOF analysis of a single blast pressure loading acting on a SC panel with either fixed or simply-supported boundary conditions. The programs can also be used to generate iso-damage pressure-impulse diagrams for a given pressure pulse shape. These programs allow quick analysis of SC panels to blast loadings for use in a parametric study or initial design stages of sizing a structural member.</p>

<ul>
<li>Program "SC_SDOF_FIXED_V1_7.m" conducts a SDOF analysis for a single blast pressure loading on a SC panel with fixed boundary conditions. The program version is 1.7.</li>
<li>Program "SC_SDOF_SS_V1_7.m" conducts a SDOF analysis for a single blast pressure loading on a SC panel with simply-supported (SS) boundary conditions. The program version is 1.7.</li>
<li>Program "SC_SDOF_FIXED_PI_MAIN.m" conducts SDOF analyses to develop iso-damage pressure-impulse (PI) diagrams for a given pressure pulse shape on a SC panel with fixed boundary conditions. This program uses "SC_SDOF_FIXED_PI_V1_5.m" as a subroutine for creating the PI diagrams. The program version is 1.5.</li>
<li>Program "SC_SDOF_SS_PI_MAIN.m" conducts SDOF analyses to develop iso-damage pressure-impulse diagrams for a given pressure pulse shape on a SC panel with simply-supported boundary conditions. This program uses "SC_SDOF_SS_PI_V1_5.m" as a subroutine for creating the PI diagrams. The program version is 1.5.</li>
</ul>

<p>The input parameters for the programs and the operations performed in the program are fully described and annotated within each program file at each step of the program. Further background information and validation of the expressions used within the programs are described in detail in the reference below.</p>
