In this tutorial, the use of DLOAD and VDLOAD subroutines for defining the laser pressure in the Laser Shock Peening process is explained according to two papers.
The pressure induced by laser shot is not uniformly distributed and has a complex function depending on both time and position.
To define such complex function, DLOAD or VDLOAD subroutines must be used according to the defined step in the Abaqus step’s module.
In this tutorial, both the single and multiple shot simulations are discussed in detail.

Package 1 description (Simulation via Dynamic Implicit step):
cost: 25 EUR (must be paid by the PayPal or other payment methods according to your country)
included files: Abaqus files (CAE, JNL, modified INP and DLOAD subroutine files) for single and multiple shots simulation, the reference papers and a read-me file for some explanations.
models are created by using Abaqus 6.14 (2014)
level: advanced

Package 2 description (Simulation via Dynamic Explicit step):
cost: 25 EUR (must be paid by the PayPal or other payment methods according to your country)

Notice: Packages 1,2 and 3 do not including step-by-step videos. They only include read-me files for some explanations. But packages 4 and 5 include step-by-step videos for single shot simulation.

Package 4 description:
only includes the single shot simulation and residual stress calculation via Dynamic Implicit step
cost: 60 EUR (must be paid by the PayPal or other payment methods according to your country)
included files: step-by-step tutorial including the modeling and writing the DLOAD subroutine from scratch, Abaqus files (CAE, JNL, modified INP and DLOAD subroutine files) for single shot simulation, the reference papers.
