خلاصه
خوردگی با این که سبب کاهش ناچیز کتله در ساختارهای انجنیری می‌گردد اما باعث تقلیل چشم‌گیر در مقاومت مکانیکی و عمر مواد خورده‌شده میشود. بنابراین، حفظ سلامتی یک ساختار که در یک محیط خورنده قرار دارد، می‌تواند وضعیت ساختار در هر زمان را نشان داده و سبب جلوگیری از لطمات وارده و هزینههای ناشی از آن شود. هدف از این پژوهش، بررسی توانایی روش امپدانس الکترومکانیکی در تشخیص خوردگی می‌باشد و با استفاده از پیزوالکتریک به بررسی ابعاد عیب‌ها بر روی یک تیر یک سر بسته پرداخته شده است. جهت تشخیص کمی عیب به صورت سنتی، از معیار آسیب اسکالر استفاده شده است. با توجه به نمودارهای بدست‌آمده در بحث تحلیلی و تجربی، به وضوح دیده میشود که پیزوالکتریک در هر دو بحث قادر به تشخیص ابعاد عیب‌ها می‌باشد.
