Finally, this method was validated by being successfully applied to foams of the same base material but different densities.ĭue to the high degree of randomness in the microstructure of real closed-cell foams, many reported numerical models in the literature are not able to capture precisely the local morphological features found in solid foams geometry. ![]() Next, the relations of the bulk mechanical properties of the transversely isotropic foam in the two directions with the relative density were formulated. It is found that the ratio of the two moduli of elasticity in the rise direction and in the transverse direction linearly depends on the scaling factor, so does the ratio of the yield strengths. Then, the influence of variation of the scaling factor, which transformed an isotropic microstructure to a transversely isotropic one, on the mechanical properties were investigated numerically. Firstly, the elastic modulus of the base material was determined through nanoindentation and the macro compressive stress-strain curves in three orthogonal directions were measured for the Divinycell H100 foam. This paper proposed a method to predict the bulk mechanical properties of transversely isotropic closed-cell polyvinyl chloride (PVC) foams based on the numerical analysis of microscopic models. tomorrow while Imus tries to bounce back against AMC-Cotabato at 5:30 p.m., also at Rizal Coliseum.The bulk mechanical properties of a foam are strongly related with the modulus of elasticity and yield strength of the base material and the geometric features of the foam microstructure. He only converted 10 out of his 30 attempts from the attack line.Ĭignal, meanwhile, guns for win No. ![]() Hero Austria finished with a team-high 12 points but was shackled by the Cignal’s solid net defense. Bugaoan capped Cignal’s romp with back-to-back blocks on Janjan Rivera and Francis Saura. The HD Spikers then dominated the third and led by as many as 11 points, 22-11, after an Njigha off the block hit. He was referring to his wards’ failed bid to post a record elims sweep without dropping a set after the National U Volley Builders forced them to a four-game duel before yielding, 18-25, 17-25, 25-23, 22-25.Īfter warding off Imus’ tough stand in the opening frame, Cignal pulled away late in the next with Miguel and Chu Njigha spearheading a decisive 6-0 closing run that shattered a 19-all count. Why? Because they performed well, even though last game, we were down,” HD Spikers head coach Dexter Clamor said. The heavy-hitting Espejo finished with 19 points off a 15-of-19 attacking clip to go along with four blocks while skipper Ysay Marasigan backed him up with 13 points and Wendel Miguel and JP Bugaon added 10 and eight markers, respectively, for the HD Spikers, who wrapped up the victory in one hour and 24 minutes.Ĭignal also banked on its net defense to thwart the fourth-seeded AJAA Spikers’ offense, coming through with 14 rejections against their rivals’ five-block output at the start of the round robin semis. ![]() MARCK ESPEJO’S efficient game powered Cignal to another straight-set romp over Imus-Ivy Tuason Photography, 25-23, 25-19, 25-15, Wednesday as the HD Spikers kicked off their the finals drive in the same fashion they closed out their sterling eliminations campaign in the Spikers’ Turf Open Conference at the Rizal Memorial Coliseum.
