Yüksek mukavemetli sac metallerin kullanımı ile kaza anında yaşam mahallinde oluşması muhtemel risklerin azalacağı düşünülmektedir. Böyle bir riskin oluşumunu azaltmasının yanında daha ince sacların kullanımıyla araç ağırlığını azaltarak yakıt sarfiyatını azaltacak olan yeni nesil çelikler olarak adlandırılan Ultra Yüksek Mukavemetli Çelikler (AHSS) üretilmeye başlanmıştır. Bu tür çeliklerin yüksek mukavemete sahip olmasının yanında, düşük % uzama miktarına sahip olması şekillendirebilirliğini düşürmektedir. Sac metal malzemeyi uygun yerde kullanılması için gerekli olan sınır çekme oranına sahip olup olmadığı kalıp tasarlayarak deneme yanılma yöntemleriyle hem zaman hem de maddi anlamda büyük kayıplar meydana getirmektedir. Bu çalışmada söz konusu kayıpları önlemek için Ultra Yüksek Mukavemetli DP800 çeliğinin oda şartlarında sınır çekme oranını (SÇO) Stampack 7.2 simulasyon programı kullanılarak 2,18 olarak belirlenmiştir. Böylece üretimden önce istenen yerde uygun şartları sağlayıp sağlamadığı tespit edilerek söz konusu kayıpların önüne geçilmiş olacaktır.  ", "language": "tr", "english_title": "Determination of Limiting Shrinkage Ratio of Ultra-High Strength Sheet Metal Materials by Numerical Analysis Method", "english_abstract": "In the automotive industry, in addition to reducing vehicle weight, the use of sheet metal materials with higher resistance in the event of a collision is increasing. It is believed that the use of high-strength sheet metals will reduce the potential risks in the passenger compartment during an accident. To reduce such risks, and to lower vehicle weight and reduce fuel consumption through the use of thinner sheets, new generation steels called Ultra-High Strength Steels (AHSS) have begun to be produced. While these steels have high strength, their low elongation percentage reduces their formability. Determining whether the sheet metal material has the necessary limiting shrinkage ratio for its appropriate use by designing molds and using trial-and-error methods results in significant losses in terms of both time and money. In this study, to prevent these losses, the limiting shrinkage ratio (TSR) of Ultra-High Strength DP800 steel under room conditions was determined as 2.18 using the Stampack 7.2 simulation program. In this way, by determining whether the desired conditions are met at the location before production, these losses can be prevented.", "doi": null, "doi_url": null, "resource_url": "https://www.set-science.com/a/f89f9a6a-bdca-4ff4-b0b4-65c49cf8aaf2", "pdf_url": "https://www.set-science.com/a/f89f9a6a-bdca-4ff4-b0b4-65c49cf8aaf2/pdf", "og_image": "https://www.set-science.com/assets/img/og-card-v2.png", "authors": [ { "public_id": "ea878e47-f599-49c1-b261-f101d3feaa05", "given": "Nuri", "family": "Şen", "full": "Nuri Şen", "literal": null, "orcid": null, "orcid_url": null, "email": "nurisen@duzce.edu.tr", "corresponding": true, "sequence": "first", "affiliations": [ { "name": "Makine Mühendisliği, Düzce Üniversitesi ", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] }, { "public_id": "e517ab10-5371-42fa-82eb-5bed20ec2d97", "given": "İlyas", "family": "Uygur", "full": "İlyas Uygur", "literal": null, "orcid": null, "orcid_url": null, "email": "ilyasuygur@duzce.edu.tr", "corresponding": false, "sequence": "additional", "affiliations": [ { "name": "Makine Mühendisliği, Düzce Üniversitesi ", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] }, { "public_id": "35fb9c10-b960-4478-ab4a-a078fffb84c2", "given": "Mert", "family": "Kılınçel", "full": "Mert Kılınçel", "literal": null, "orcid": null, "orcid_url": null, "email": "mertkilincel@duzce.edu.tr", "corresponding": false, "sequence": "additional", "affiliations": [ { "name": "Makine Mühendisliği, Düzce Üniversitesi ", "department": null, "country": null, "country_code": null, "ror": null, "ror_url": null } ] } ], "keywords": [], "translations": [ { "language": "en", "title": "Determination of Limiting Shrinkage Ratio of Ultra-High Strength Sheet Metal Materials by Numerical Analysis Method", "abstract": "In the automotive industry, in addition to reducing vehicle weight, the use of sheet metal materials with higher resistance in the event of a collision is increasing.
