resonate for
1. Does "resonate for" mean "reflect and commemorate"?
2. Does "the material of soldiers’ lives" mean "soldiers' lives as the material of painting"?

Context:
Collective memory manifests itself in many ways. With war art it enables a single painting – Alex Colville’s Infantry near Nijmegen, for example – to resonate for many of the thousands of Canadians who served in the Netherlands during the Second World War. The canvas is a tapestry of still-life elements – the material of soldiers’ lives interwoven into the fabric of the artist’s imagination.

Answer

1: No. I think that resonance in this context means something like 'bring back memories', or 'elicit emotion'. The painting reminded them in a way that a simple memorial would not.
2: No, I don't think so. I think it is referring to the day-to-day things that are part of a soldier's life.

Answer

Ressonate means to oscillate. As when you have something bendy and springy and wave it about so that it wobbles backwards and forwards.
A property of things that resonate is that when you give them a shove, something to get them started, they keep oscilating, perhaps even growing in amount.
Two similar thungs close together may get each other started resonating.

Here to resonate is the same concept. The art, creates more emotion in people who identify with it; it resonates with them, setting up things in them.
So reflect, is part of it, as this is part of creating the emotion.
