Crack detection

The aims of this study are to develop and apply the method of using frequency response functions to diagnose cracks in elastic bar and beams structure. The contents of the study includes: building models of cracked elastic bar and 3 beams structure; studying the changes of oscillation parameters, mainly frequency response functions due to cracks.

SoftICe 4.05 for 9x, NTCông cụ debug khá mạnh tuy nhiên chuyên làm Win bị Ice Numega SoftICE Driver Suite 2.6 for XP ; mình thường dùng vì nó ít làm PC bị đóng băng Smart Check 603(601 cũng đươc): debug for VB (chạy tốt trên 9x) Quaid Analyser :debug for DOS mình không dùng Win9X nên không dùng các dubug for 9X như TRW2k, nếu các bác dùng Win9X thì hãy dùng nó b.Debug add_on: BreakICE for SoftICe4.

Và như được lập trình sẵn ta lại làm :) : Dùng PEid v0.92 để Detect , chúng ta biết chương trình được pack bằng UPX 0.89.6 - 1.02 / 1.05 - 1.24 - Markus & Laszlo . Ta dùng tool : UPX Unpack để unpack chương trình này , hoặc chúng ta cũng có thể dùng Plugin của PEiD (có ReBuildPE ) để unpack
