Agarwal, G. (author), Kumar, A. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Solidification cracking susceptibility during laser welding was studied experimentally and numerically in advanced high strength steel sheets, namely transformation-induced plasticity (TRIP) and dual phase (DP) steel. Using the same heat input, laser bead-on-plate welding was carried out on single sided clamped specimens at various starting...journal article 2019

Eftekharimilani, P. (author), Gao, H. (author), Huizenga, R.M. (author), van der Aa, EM (author), Amirthalingam, M. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Advanced high strength steels (AHSS) are increasingly used in automotive industry; thousands of resistance spot welds are applied to car body-in-white. High alloying levels of AHSS result in lower weldability. Residual stresses play an essential role on the formation of defects and the mechanical performance of the weld. An electrical-thermal...conference paper 2018

Agarwal, G. (author), Gao, H. (author), Amirthalingam, M. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Advanced high-strength steels (AHSS), which are increasingly used in the automotive industry, meet many functional requirements such as high strength and crash resistance. Some of these steels contain high amounts of alloying elements, which are required to achieve the necessary mechanical properties, but render these steels susceptible to weld...conference paper 2018

Agarwal, G. (author), Gao, H. (author), Amirthalingam, M. (author), Hermans, M.J.M. (author)Susceptibility to weld solidification cracking in transformation-induced plasticity steel sheets was studied using a modified standard hot cracking test used in the automotive industry. To vary the amount of self-restraint, bead-on-plate laser welding was carried out on a single-sided clamped specimen at increasing distances from the free...journal article 2018
