no code, but some ideas. First get the UVs of the impact, probably try to use the PickedUV as seen in the code archives. Then use copyrect to place a small shockwave texture on the bigger main shield hull texture. Use this in blendmode 3 (additive), plus some kind of animated plasma texture on an additional texture layer.
The small shockwave texture may be a sequence of frames, animated and fading to black.
However, using copyrect may be pretty slow, even when you use the texture flag 256 to make texture access faster.
