The problem concerning the stress-strain state of a plate under impact load with various intensity levels of collision momentum applying finite-element method was considered. The problem concerning transversal impact of a body in form of a mass point or a finite body to the sheet-formed structures of following type: a plate, a plate strengthened by ribs, a plate with damages was considered. Problem design diagram, design diagram of plate, fields of deflection intensities distribution w for plate central surface, stress distribution fields of the plate based layer, stress distribution fields of the plate based layer equivalent stresses sigma eq =f(m), relations for sigma eq = f(m) and w = f(m) at variation of impact initial velocity, impulse form of view, deflection and equivalent stress sigma eq intensity distribution diagrams in cross-section Kn depending on view form of impulse, the diagram of plate's deflections, the stress field sigma eq of the plate caused by impact body of finite dimensions, the field of deflection intensity distributions w for damage plate, the field of equivalent stress intensity distributions sigma eq for damage plate, the structure diagram of plate with stringers, the deflection field of plate with stringers, diagrams of equivalent stresses sigma eq of plate with stringers in central cross-section along axis x at damage deeps are presented in the paper.
