“…Perfectly plastic-elastic material cause the stress and strain increases up till the yield points then the stress become constant while the strain increase. in the case of the concrete, concrete in the damaged plasticity model is suitable for representing the complete inelastic behaviour of concrete with tension and compression, which makes it viable for damage simulation [19][20][21]. the effective tensile and compressive cohesion stresses can be determined using the following eq.…”

Finite element AnAlysis on structurAl BehAviour oF Geopolymer reinForced concrete BeAm usinG Johnson-cook dAmAGe in ABAQusthis paper details a finite element analysis of the behaviour of si-Al geopolymer concrete beam reinforced steel bar under an impulsive load and hyper velocity speed up to 1 km/s created by an air blast explosion. the initial torsion stiffness and ultimate torsion strength of the beam increased with increasing compressive strength and decreasing stirrup ratio. the study involves building a finite element model to detail the stress distribution and compute the level of damage, displacement, and cracks development on the geopolymer concrete reinforcement beam. this was done in ABAQus, where a computational model of the finite element was used to determine the elasticity, plasticity, concrete tension damages, concrete damage plasticity, and the viability of the Johnson-Cook damage method on the si-Al geopolymer concrete. the results from the numerical simulation show that an increase in the load magnitude at the midspan of the beam leads to a percentage increase in the ultimate damage of the reinforced geopolymer beams failing in shear plastic deformation. the correlation between the numerical and experimental blasting results confirmed that the damage pattern accurately predicts the response of the steel reinforcement si-Al geopolymer concrete beams, concluded that decreasing the scaled distance from 0.298 kg/m 3 to 0.149 kg/m 3 increased the deformation percentage.Keywords: fly ash geopolymer; geopolymer concrete; finite element analysis; Johnson cook damage; ABAQus software 4 uNiversiti MAlAYsiA Perlis (uNiMAP), fACultY of MeChANiCAl eNgiNeeriNg teChNologY, MAlAYsiA

“…Thus the modified Bree problem [18,19] has been introduced for arbitrary thermo-mechanical load histories. Many approaches have been proposed to solve the Bree-like problems for engineering structures, including the analytical approach [16,18], incremental Finite Element Analysis (FEA), the Direct Cycle Analysis (DCA) [20][21][22], the Noncyclic Method [23,24], and the direct methods [25][26][27][28][29][30][31][32][33][34]. Based on FEA simulation, the direct methods consider the static theorem by Melan [35] or the kinematic theorem by Koiter [36] and features high computational efficiency.…”
